I’m done

I need to vent and I’m seriously done with the relationship after today it’s been dragged on long enough. I feel like my boyfriend still has feelings for his son’s mother remind you she has found me on Facebook saying how he’s been trying to talk to her and flirt with her. Inviting her over to the house when I’m not there.. this is what she’s saying. And she’s speaks on how he still has yet to see his son. He was trying to make me think it was her fault the reason why he can’t see him. All of this mess happened like two months ago. He tried to make it seem like she was a liar and when I was asking him to leave he refused. Me being dumb I just let whatever she said slide because I do know how people can make up things but I was giving him the chance to finally get his son since what she says was false from what he says anyway and she said she wasn’t holding her son back from him. He still haven’t got him. His own brother picked him up one day and took him to the water park when it was hot and posting my boyfriend son on his page since his brother haven’t seen his son in a while either. My boyfriend screenshots the pics and post it on his page smh. Let’s go back to yesterday he has a daughter as well and he says she wants to come over this weekend and he said before all that drama happen 2 months ago that he hates getting one child and not the other. He then says it again yesterday and I got upset kinda because it’s an excuse now. His son doesn’t live far from us so he can see his son. His daughter comes with no problem. I feel like he has feelings for her still and if he can’t get what he wants from her( sex, getting back together) I’ve seen screenshots recently from his sons mother) he doesn’t want to deal with his son. It’s like he says oh I don’t want one kid without the other just to make him feel better because what he says is bs for the past year I haven’t met his son ever! I wouldn’t even know he was texting his sons mother if she hadn’t told me he was making it seem like he wasn’t and she blocked him. Her messaging me was all on Facebook and we’re not friends on there.I’m done with him. I walked out the house today and went to work and he got mad and blocked me because I didn’t wait for him. I’m over this dude.
