Saturday was my birthday. Ex came over, made breakfast and a cake with the kids. very grateful for that. Immediately after that, shit hit the fan. Unnecessary fighting and telling me how I deserve to feel all this hurt from the separation and her moving on. I got ready and was going to take the kids out. She jumped up and rushed out the door with them without saying anything completely throwing a wrench in my plans. Few hours later she brought them back, didn't say a word to me. I went to a family members for the night (first night out in a long time). I came home yesterday and right away, she was losing it on the kids (they were being extra spicy). She popped off and told my youngest she didn't like her and that if this behaviour keeps up she's not allowed to come to her place(when she gets one). I cut in, told my ex to go calm down and I calmed down my daughter. After that I went in to talk to my ex and she was crying about how she's a shitty person and this and that and how I tell her she's shitty all the time. I said "I don't think you're a shitty person, but the way youve treated me has been incredibly shitty". She LOST IT. Jumped up and pushed me into the door frame and started punching me in the head and my back (I turned around so the story couldn't be twisted on me). I looked up, and saw my oldest daughter sitting in her bed bawling her eyes out from what she just witnessed so I ran to make sure she was okay and let her know I was okay while my ex smashed a bunch of things in my room. Once the kids calmed down I went to talk to my ex again because she started talking about killing herself and even after that, I still wanted to make sure she was alright. She was numb and her eyes were dead. After checking on her, it turned Into her talking about how she's going to fuck multiple people in my bed and send me the videos, and that I'm worthless and deserve to feel hurt. I dont know what to do other than document it all. She hasn't been herself to me or the kids since the separation started a few months ago (which she initiated). She had an extensive list of mental health problems which I've tried to warn her I'm seeing signs of. If I file a police report she can lose her job. Me and the kids deserve more than this. Im traumatized by this whole thing and now Im going to need to find a therapist for the kids as well. I know my ex better than any one, and know this ISNT normal for her. Whether she cares about me or not, I do still love her and want her to get the proper help so she can be the great mom she was before. It's all so volatile and everyone is on eggshells.
