Would You Date an Hiv+ person?

I have an HIV positive girlfriend. its been 3 months now since we met. serodiscordant couples is what Doc calls us. I met her at an HIV/AIDS hospital and we talk. we just connected immediately. she thought i was Hiv+ as well and i lied i was for a month. I was insecure she would leave me if i told her i wasn't, it seemed like the reason she bonded with me was because she thought i was also positive. at first i thought we would just be friends but things just went too far too fast. my brother told me to just leave her but honestly i love her. i want to be with her. she loves me too. i told her about my hiv status and she felt betrayed but still accepted to be with me if i was willing to be with her. The Doc advised me to get started on taking PREP which i did. My girl takes her meds everyday and her viral load is undetectable,i take my prep meds everyday as well(if you dont know what prep is i have no time to explain). i will not tell any other family member about the hiv status of my girl because they will tell me to leave her just like my brother did and yet my brother is a Doctor i thought he would understand but i was wrong. Some people just don't know what it means to love someone.
