Help, my wife is HIV positive!

I was in a serious relationship with a girl for two years, which was to lead to marriage. Late last year, she gave birth to a baby girl. During the two years we stayed separately but visited each other often. When she gave birth, she proposed to move into my place but being busy at work, I suggested she stay at her place for about a month since her friends could give her the much needed assistance and care. This was also to give me ample time to plan. Upon discharge, I enquired about some strange medicine she had been given meant for the baby and she told me she was HIV positive. Two weeks after this incident, we went for VCT (the three of us) where I tested negative and she tested positive. The child was not tested. This was really a very difficult time for me and we were directed to a counsellor, an idea she flatly rejected arguing that counselling won’t change anything. My problem is that I have a very strong connection to her but I am not sure if I should move on or continue with our relationship. She has refused to take ARVs and now I’m worried for our daughter. Is our daughter at risk of contracting HIV through breastfeeding? What should I do? {HRS}
