He left me and infant without a word..

We’ve been together for 2.5 years. We together have a 3 month old son. He has a 7 year old also. They moved in with me 2 years ago. He never paid rent after me asking many times... I was a mother to her. I told him he needed to pay me once baby came. He did for 2 months then the second month he kept pushing it off and just gave me $100 fri for last month.. we got into it fri bc I asked for help for May and June and that’s all he sent me. Then he got mad at me for asking if he’d be home for baby’s bedtime.. he hates that, but he barely sees our son so I ask so I know if I should keep him up a little longer if he’s gonna he a little late. He turned everything on me and started saying he hates the house bc it’s my house and that I have all the power w our son and the house.then he came home and he ignored me since Friday!!!! I worked nights sat sun mon and Tuesday and my friend came over int he morning wed to watch our baby at 5am until I got home at 8am, since we overlap shifts and she told me he was packing all his things and moved out in front of her!! Without a word! I didn’t text him or anything.. he finally texted me around 7pm saying let me know when you need me to watch him.. uhm “watch???” You mean parent ..

I should make mention I had been thinking about sitting him down and talking to him . You know like adults and bringing up the money and everything and if he couldn’t contribute making him leave.

Ugh any advice... currently interviewing sitters to watch our baby, bc now I know I can’t rely on him. And plus if he can’t pay anything he should come and see him when it’s convenient to him. Idk what to do.

His step mom and dad told me he’s always been a compulsive liar and manipulating .
