You want to believe that and when you read Andrew's story, you may at first find his actions noble.
Andrew (not his real name) had been going out with his girlfriend for two years when they learnt she had full-blown Aids.
He decided to marry her and continued having unprotected sex with her.
Now he is HIV positive. Both of them now need looking after.
Crazy in love or just crazy?
Stories like Andrew's led Action for Aids to organise a getai as part of its I Am Responsible campaign, targeted at heterosexual men. It promotes the importance of practising safe sex, use of condoms, and going for tests.
Andrew, 53, met his wife when he was 41 and she was 39.
Some of Andrew's details have been changed to protect his identity. People with HIV cannot be identified by law.
Andrew described how they met.
He said: 'I met her at a lounge where she worked as a manager. She was divorced with two children, and I was divorced with a child.
'We got along very well and we started living together shortly after we met.'
Two years into the relationship, Andrew said his wife became very ill.
'She lost 9kg in less than a month, and for two weeks, she kept having a high fever every day.
'She also had ulcers around her mouth and lost her appetite. We went to see a doctor six times but there was no improvement.
'Finally I took her to the emergency department of Changi Hospital, where she was admitted. They ran a blood test, and three days later, the doctor there informed us that she had full-blown Aids,' said Andrew.
When he heard the news, he immediately went to the waiting room to tell her children who were in their 20s then.
'I wasn't married to my wife then, but I told her children that I had no regret, I would take care of their mother and I would take full responsibility for her,' said Andrew.
'My first reaction was to stay calm. My wife kept crying, and she became very depressed and went into a daze,' said Andrew.
'Nobody would believe me, but I never got angry with my wife, because I loved her very much, even until today, and I never blamed her for anything,' he said.
He said he believes her story of how she got infected with the virus.
She said she might have contracted the virus when she went to Nigeria once in the 1980s, when she was working as an air stewardess.
Said Andrew: 'She told me she had malaria in Nigeria and had been admitted to the hospital and had been given a blood transfusion there. She suspected she got Aids from there.'
Andrew never questioned his wife about her previous relationships or if she had multiple sex partners. He just doesn't want to know.
'Ignorance is bliss and if I know too much, I will get upset and the feeling I have for her would not be the same,' he said.
She was transferred to the Communicable Disease Centre, where she was put in an isolation ward.
'I visited her every day, but the staff there wouldn't let me stay with her as long as I wanted because they said I was not related to her,' said Andrew.
Two months into her stay at the CDC, Andrew finally decided to marry her.
'I was frustrated that my visiting time was limited since I was not related to her, and she was all alone in there. She had no friends visiting because she did not want to tell anyone about her condition. She was lonely and depressed,' he said.
The couple applied for time off from the Communicable Disease Centre and went to the Registrar of Marriages to solemnise their marriage.
Andrew said his family did not approve of the marriage and continued to voice their objection after the marriage papers were signed.
They suspected she had some form of illness and did not want him to marry her.
Andrew then refused to go for an HIV test, despite being told by his wife's doctor to do so, and even continued to have unprotected sex with his wife after she was discharged from the CDC.
'I never used a condom in my whole life, and with my wife, she knew I did not like it, and she also never asked me to, even after we found out she had Aids'.
It was only two years later when he himself had a high fever, he went to the CDC to get tested, and found out he was HIV positive.
'My wife was with me, and she held my hand. I remained calm, because I had already expected the result to be positive,' he said.
'But I saw the way she looked at me when the doctor told me the result and there was pity in her eyes for me,' he said.
Life for the couple who live alone has been hard, both financially, and emotionally.
His wife had to quit her job after she was discovered to have Aids, as she was too sick to work. They also ran into financial difficulties as the first round of medicine she had to buy cost them $900.
Andrew also lost his monthly income from his previous job when he was retrenched.
They later found a cheaper alternative for medicine from Thailand, which cost $80 a month.
Currently, they fork out about $170 every month for medication for the both of them.
Andrew takes home a monthly salary of $700 from his job.
He also owes his relatives several thousand dollars.
'I had to borrow money from them last year as I couldn't find a job and I had a lot of outstanding bills to pay,' he said.
Taxi fares are one of their main expenditures as they have to be careful not to walk in the sun, or get caught in the rain.
'We have to be extra careful as we cannot afford to fall sick, and the medicine we take gives us a lot of side effects, like swollen legs, aches and pains, and we get exhausted easily,' said Andrew who was coughing as he spoke to us.
He said he goes to bed full of worries every night.
'I feel very tired, not just physically, but my soul is very tired as well. I feel very bad lying to my family, and I am afraid they will find out the truth should I die one day. I also worry about who will take care of my wife after I am gone,' he said.
Andrew is now fearful of spreading the virus to his family.
He said: 'I try to avoid letting my grandchildren kiss me, and I make up excuses not to kiss them. I also try not to share food with my family.'
Andrew said said he volunteers at Action for Aids to help counsel patients with Aids but had never told his family he is HIV positive.
'I don't know if they suspect. I know that if they find out I am HIV positive, they may not ostracise me, but they will hate my wife. I don't want them to be upset with her,' he said.
Andrew visits his daughter and stays over at her home. He takes care not to let anyone see him taking his medication.
'I also try not to cough in front of her, and I try to control myself until I am in my own room then I let myself cough,' he said.
LIVING A LIE
Andrew, who is 1.7m said he lost weight from 80kg to 65kg in the past 10 years.
He said: 'I feel lousy every day because I am living a lie. I lie to my family, I lie to my colleagues, and I lie to myself.
'Every day when I wake up, I must tell myself I am normal, I am well. Then at work, I pretend I am healthy and I joke around with my colleagues. But at night, when I reach home, my bones ache, and my knees get swollen, and I feel very exhausted,' he said.
Andrew said he has previously interviewed three times by researchers from a university, and said he has been happy to do so.
'I don't mind people asking me these questions because I want to share my experiences, and educate the public on how to live with people with HIV or Aids. I hope that the public will not condemn people with HIV,' he said.
