Right now you are grieving a loss. It's perfectly normal! We've all been there to some degree, friend. It's not pleasant, but, you will grow from this and learn to move on. You said a friend was pulling away from you. She might not know how to tell you she really cares about you -or- she was never really your friend. Time will tell.......
I believe it's against the law to willfully infect someone with HIV. People go to jail for doing this.
That said, I hope he was talking BS.
One of my best friends has lived with AID's for over 30 years now. He lives life to the fullest and then some! Having HIV is far from a death sentence. There are tons of support for people living with many diseases in this day and age.
I'm a firm believer that when negative things happen in life you have to let it go and move on. Yes, grieve, yes feel sad for a while and question why, but MOVE ON.
You can do it, friend! Life is way too short to dwell on the negatives.....
