Am i fucking stupid

Every relationship i've ever been in always end in total shit fest. Woman are fucking insane. I know I'm far from perfect but I try and if they need something I'm the first to bend over backwards to get it. In my last relationship I met this girl I knew she had a kid and we were talking. So one night I texted her asking if she wanted to hang out and she agreed. I knew she lived with her parents so I assumed that her parents would be watching the kid. Nope she just rolled out to come chill with me. She later got a text her parents kicked her out for not watching her kid. I felt terrible in many ways this girl is homeless now , but god damn why is no one watching your kid. This should have been my first sign to turn and run but she ends up staying with me at my grandmothers place and bouncing between hotels. I admit I was having fun but I felt awful about this situation, even told her that, her response don't fuck with a witch. umm ok . Am I fucking stupid? So I buy a truck and put some more money together so me and her could get an apartment, Major fuck up number two I work for cash and didn't have a bank account so I let her put it in her name but it was ok because we were both trying to escape the same thing and at this point I really did love her, or maybe we just dropped to much acid together at a festival and I thought I did. But either way we were living together things were getting paid and it was all good for awhile until she decided to quit taking her meds beat me up destroy my plants and put my shit out. I REALLY AM FUCKING STUPID. This isn't my first rodeo though. my first rodeo kicked the shit out of me as well but not like this one. The problem is though I'm learning things I already know. not again
