We broke up
I finally ended the relationship. We were together for over four years. I thought his kids liked me. I was wrong. I thought his mother liked me. I was wrong. I was fond of his kids and cared about them but they were very disrespectful towards me at times and towards the end it only became more frequent and had gotten worse. He would side with them and defend their behaviors. It was his parenting. He also has a lack of being forthcoming about many things and when I confrotned him we would lash out at me. I was accused of being possesive and he lashed out at me because I caught him lying to me about some things regarding his ex. I glanced at his phone a couple of times which was sitting out (I didn't look through it, texts were popping up on the screen) and saw text threads of overly friendly, semi- flirtaitous conversations he had been having with his ex (apparently they had been hanging out at her place "for the kids" sake without him mentioning it to me even though we talked daily) and conversations between him and a female friend of his from college discussing our relationship problems and him not portraying me in a very good light). He went off and accused me of looking thru his phone and being a possesive stalker. I'd had enough. His coddling mother (MIL) also accused me of being possesive and not being good mother material since I wouldn't ignore his kids poor behavior and revolve my life and money around only him and his kids. Don't even get me started. Anyways I ended things finally and I am grieving and hurting but deep down I know this is the right decision. I don't know what I did wrong. Maybe I could've handle things a lot better.
