30/M. Only one relationship my entire life. I have no idea how to flirt, so I always wait for girls to come to me to avoid being creepy. I finally got a relationship back in Feburary. But it was very toxic. I wasn't perfect either, but she was telling my friends lies about me after we broke up and made me out to be a stalker and harasser. 

She would also say fucked up shit to me, and even hit me one time just because she demanded to go through my phone and when she found a chat of me talking shit about her to a friend of mine.

Anyway, I really want her back. Everyone on reddit and even friends say to cut her loose because she's mentally ill (she chose to be homeless over living with her parents who aren't even abusive). But, I don't want to be alone.
