This is a very difficult question, as issues of telling or not telling as well as when and why differ hugely in the different cultures.<\/p>\n
I understand that you come from a very traditional culture in India and this puts a major social pressure on you. It is difficult for me to say what is right and what is wrong in your situation. What will be considered wrong in all the cultures and countries, however, is if you infect your fiancee with HIV, without giving her the choice. I mean, if you intend to have unprotected sex with her, she needs to know that she is exposing herself to a risk of catching an infection that can be potentially life threatening in the long run. She must have the choice of whether she will get that or not.<\/p>\n
If this was happening in the Western world, I most probably would have also mentioned the fact that in many countries the intentional (knowing) transmission of HIV, or even putting a person at risk, is prosecuted and people may be sent to prison. I, personally, may not approve of this legislation, but in places it exists. I do not know what is the situation in India regarding this.<\/p>\n
