Thank you for all of the support. It sucked. I'm feeling like I made the right choice, but this morning I realized that he just blamed me for everything. That I was running away. That I wasn't communicating. That I didn't want to move in. A bunch of quacking, but at the time it just felt like I couldn't say anything that I felt confident about. Luckily I did it and walked out without giving in. I just wish now that I had led with "this isn't working for me" instead of talking about things that bother me.
BUT I've already gotten a text from him saying "I love you and I want to fight for you". So I don't think he'll make it easy in the days/weeks to come. Which makes me just want to throw things.
