Pregnant & he left me for someone else

How do I cope with this during my last trimester? I feel like I only have my mom and one friend.

First off, we had issues, so it wasn’t that he just met her and left me. But as we were trying to work on our relationship, looking for a place together, he was coming to appointments etc, one night he just disappeared and said he couldn’t love me like he used to. Everything was over text.

My crazy ass put a tracker on his car a couple days later and sure enough he was going over to another girls house basically every night, and out and about. (this was almost 3 weeks ago) so of course he was talking to her behind my back at some point. He’s even outright said something in regards to her being unattractive before.

I went no contact with him and he ended up texting me a few days ago saying “I hope you’re doing okay” Yeah okay, fuck you.

End rant
