Relationship

I have given this man 100s and 100s of chances tried 2 breaks until I finally broke up with him it’s been almost 8 months and he won’t move out. During those 8 months he was supposed to be working on himself for me and his son. I tried trusting him and listening to him but he wouldn’t let me on his phone. I then saw a whole bunch of woman snaps on his notifications. He told me he added them January and regrets it and kept thinking about deleting them and the app. Fast forward to now the other night I managed to somehow log into his snap as idk his phone password. They were all there he couldn’t last a week since I last found out. Complimenting them replying to there stories. Sexting. Saving every pic in chat. While I was treating him like gold besides being sad a decent amount of times because of be-trail I have given him everything. I’m in so much pain I don’t know how I’m supposed to be single and raise our baby on my own. I don’t know how to get him out of the house. He is angry and scary and has grabbed me abit to tight. He is mean and cold but also says the right things and can be so sweet and lovely. Seeing all the messages and photos have really hurt me idk what to do. I wish I didn’t meet him and knew who he really was before making him the father. He wants me to add guys says his relieved I know and that now he can actually get better and it was weighing down but it’s crap although it hits a point in my heart. I feel so betrayed I was so loyal hoping he would get better but he won’t leave and I can’t leave I have nowhere to go no friends no family no support.
