u seem to be caring more for your bf than yourself u were wrong to have sex without a condom because of hiv and stuff. your mother seems reli nice and if u want after ur bfs courts tell him to move back to your dads with you so ur dad cant sexually molest you. i know how you feel because i was sexually abused my my dads best friend when i was 6 good luck.
