I think my marriage is over.

My husband and I have known each other since we were kids he's 5 years older than me so it wasn't like we were Best friends growing up but we were cool. We have been together for almost 5 years married for a little over 2 years. We have been through our fair share of ups and downs but, I have always been the one to be like no we love each other and are married we can't just give up on each other. He says his issue with me is I have an attitude problem and that I don't trust him. My issues with him are he is untrustworthy and he refuses to stop doing things that cause problems for us. Every time I turn around he has another female in his phone or something along those lines. He always has an excuse for why. Then he recently I guess went on my Facebook and noticed that on my daughter's page and noticed that my ex's sisters was on her page and was going off about that but he insists on keeping in contact with people from his past relationships and infidelities. For instance I have access to his FB page and I seen that he had sent a friend request to a female from where we used to live that I caught them texting each other inappropriate stuff. He also knows that I'm not okay with him watching porn or half naked videos on Facebook and he is not okay with me watching stuff like that of men but yet he still does it no matter what. Everytime we get into an argument he's so quick to pick at everything he wants me to change yet defends his actions. I'm almost 31 weeks pregnant with our first kid together although he's been father to my other kids but I think we are at a point of no return. I'm so depressed that I literally just want to sleep until I have my baby. I hate the thought of being divorced but I feel like that is where we are at! 😭🤦🤰
