I am still insanely in love with my ex and don't know how to handle her accusations

I'm very confused about myself. It's been I think 3 to four months since I broke up with my girlfriend and a lot has happened in these four months. We argued during the first and made up the same night. We didn't talk for about two months and then she accuses me of rape. (Keep in mind I am underage and she is a legal adult now) I'm not much younger than her 16 to be exact and I just have been rereading her terrible texts towards me. How could this woman who I loved so much just up and change completely? It tears my hear apart and I don't know what to feel. I have never done anything to hurt her. I cherished her and for some reason I still do. It terrifies me that she has done this. I don't know what to do I'm upset and sad and my feelings are everywhere and she posts about it on Twitter and slanders me for no reason!!! It hurts me so much because for some reason I still love her. In these past months I haven't been able to ask any girls out or even think of dating anyone but her. I've tried my best and I just can't bring myself to get to know anyone else because I'm so stuck in the past. I have reason to suspect she is accusing me of rape because she found out I was talking to another girl. But his girl I have been talking to I would never date. She is practically my best friend! We hang out and play video games and draw together and all that and we post about it online and stuff, and knowing my ex and her extreme jealousy I can only assume that it's because she is jealous. Why she would do such a drastic thing? I do not know. But it cuts holes in me knowing she is doing this. I don't know if I should confront her about this and ask why she is doing this it just not do anything at all. I do not want authorities involved I can't deal with that in my life right now and I certainly don't want her getting kicked out of college and possible jail time because I still love her so much and wouldn't want to ruin her dreams. Any help would be appreciated.
