<human>: Can you provide a brief rundown of the text in within 3 sentences?

I broke up with my ex because I want to meet other people. She claims to have accepted it but still steals my phone, goes through my messages and we'll start all this drama over some new girl. This is the third time and I feel like I can't date this girl that i like because of this huge drama.

I am trying to remain friends with her but so far it hasn't been working. I haven't cut her off because I feel like she's gone through alot.
Her mom doesn't love her, she has few friends. And i guess she's lonely. I care enough about her to be her friend and help her out with some things. But I don't want to continue in this cycle of drama.
<bot>: Am I messed up if I cut my ex off despite the very little support she has in her life at this point?
