Hey you forgot something

My child's father and I have been going through it my entire pregnancy was I was extremely depressed I'm pregnant going through a break up with him still sending mixed signals and me accepting them because I'm still in love and wanting my "family" so bad. Skip ahead the girl he had been messing around with has been posting a bunch of shit online about them mostly just word post but then she put up a picture which I knew was old because he hasn't had a hair cut in months but it still made me furious...I'm hormonal I just gave birth 5 days ago I'm sleep deprived and I'm being freaking taunted I feel like and humiliated here I am soooo happy sharing my baby with my social media pics of baby and dad becaus we are so happy and she's talkin about a trip they are supposedly planning I would be more understanding if he said he was going to be dating her and we were done...but I feel he lies he denies seeing her or talkin to her then she comes up with some mushy status about him. FAST FORWARD I got fed up todayp told him off and refused to allow him in my home I told him take me to court because now that he's lied  and damaged any chance of a civil relationship I don't wanna see him nor is he allowed in my home. He got upset and left after we argued outside. I HAVE his son over as I always do, he left and never even said anything about his son (not mine) and here it is midnight and he still hasn't said anything. He doesn't have to go but what the hell how'd we just have a huge blow out and you leave your kid here still.
