Hi there Vishal.
I think you have a classic case of Venerophobia & pardon me for being so blunt.
If you have done 3 Elisa
tests at 6 mth intervals, there is nothing to fear. If you wish, you could do what is called a western blot test or a DNA-PCR
test to be more clear.
However, i do think you are in the clear & there is no issue. Your wife's problems appear unrelated.
HIV infection does not mean one will necessarily develop AIDS
& yes there are various treatments with something called HAART therapy that is pretty effective.
Might i suggest, you get yourself counselled by a good psychologit nearest you & allay your fears!
All the best & wish you continued good health!
