I can't do it anymore..

Ok so my SO and I have been trying to make things work for almost 2 years now. I have 2 kids from a previous relationship and my SO just doesn't understand the concept of "co-parenting" and I just can't deal with it anymore so I'm leaving. I feel like he wants me to put him before my kids and that's not going to happen. He even gets mad when I go to church? I went to church Wednesday night and I came home to being ignored. I went to bible study last night and came home to him being rude to my daughter and being ignored again? It's not like I'm going to hang out with friends to party or drink?! It's church!!!! I just can't be with someone like this...now I'm glad that this wasn't our month cause I really would have been in another bad situation as I was before. Maybe alone is the way to be right now. I just had to vent and I would appreciate any words of encouragement that u ladies could give me right now. ♡
