I need helpp

Soo I'm very confused at my situation bec I used to had a bf but we broke due to some personal reasons and I was in love with him too much then after we broke up he was still in love with so was I but after sometime when I think I had him I lost all my interest in him and now we do exchange some msgs but I don't think my feelings for him is love there comes my bsf she was my bsf but for u-8 months we were in no contact but now we js got in contact I confess all the feelings and loneliness and all things but after I confessed my feelings for her she accepted me I'm confused bec i don't have feelings for her now but I used to had feelings for her back then and plus she has borderline personality and anger issues but our friendship is 3 years old if I got in relationship with her our friendship will be ruined but idk what to do should I reciprocate her feelings or not and I recommended that let's go on a trial were in long distance friendship and busy with our studies we understand eachother but the problem is im pretty confused and don't know who to ask for opinion or suggestion's on what I should do ╥﹏╥
