My girlfriend incorrectly perceived a slight against her, and sabotaged our relationship.

My girlfriend had a misunderstanding with my ex wife. We had planned to bring my daughter over this morning. My gf forgot about that part and tried getting ex wife to take her last night.Long story short this obviously isn't a problem. We already have agreed upon everything.I end up smoothing it over. Ex wife apologizes for her part in the confusion, everything's great.GF won't hear the apology. Won't talk to me, needs to process.Inside 5 minutes later I'm telling my daughter it's bedtime when gf walks by the doorway and interjects at my daughter 'what you should really care about is daddy doesn't give a fuck about me!'Shut that down. Ended the relationship. Kicked her out.We talked calmly a few minutes later. She had literally nothing to be upset about but wouldn't hear anything. Then she tries to manipulate and abuse my daughter.I could never trust her again. It's over.Edit: more details in comments.Other info, I own my own home. Fully paid for. That my daughter and I live in. GF lived with us nearly a year.Yes she's going. No I don't think that's unfair.You people are condoning child abuse. That's disgusting.If you have a problem with me, that's fine, but children should be protected. From assholes like you.Edit 2, apparently my ex wife is coming to my defense in comments. Get your popcorn. I haven't read it. This got way bigger than I expected. But she's fuming across the room. I appreciate everyone's support. Hopefully some good comes of this somehow. via /r/TrueOffMyChest https://ift.tt/3bzZSQE
