confused://

okay so my ex best friend contacted me yesterday and told me that she used to have feelings for me and that she loved me and possibly still does. then she apologize for some things and asked me how i felt back then and i told her that i had thought she was straight so i never really allowed myself to have any feelings for her but if she would've told me back then it would have changed a lot of things for me. and she said like what and i said i wouldn't have made so many mistakes with other people and you wouldn't have had either. the thing is i got out of a long term relationship with this other girl 3 months ago and we still talk so it makes it super hard on me in life. i would like to give my ex bff a chance it's just that she doesn't know what sexuality she is and i don't think that she ever would come out at school and i'm already out as lesbian and i have been for a long time. another thing is i'm not trying to offend anyone or make anyone upset but i'm usually the more "girly" one in the relationship and towards this idk if i would have to be more of the "dudish" one. idk i'm just very confused and i could really use the help. thanks so much. ://
