So heated? 😠

So I needed to rant. I have a 2 month old baby who I do everything for as I should but mostly by myself while his dad is leaving with us and is the only one who works. So I get food stamps because he works 4 hours a day doing light work. Well I went to the store yesterday with my mom. She left her food stamp card at home on accident so I paid for her hamburger and a few other things she needed. She is taking me to the store tomorrow away so she is just going to get me what I need. My SO asked if I had any left I explained what happened. He gets all upset yelling at me on the phone. I hang up on him because I'm not no dog. Well he texts me telling me to worry about paying my own phone bill and I can go be with the person iv been wanting to. Funny thing is iv never cheated on him. He's cheated on me multiples times even when I was 8 months pregnant. He left me at the hospital after I had a c section, called me a cry baby because I cried before and after epidural wore off plus I was in labor for 25 hours. He hasn't really helped me out. I sleep in my son's room with my son because he has to get up in the morning and he don't like getting woke up by the baby 🙄 I'm with our son 24/7 I have to care for him and the house all while stressing about bills and money for diapers ect. He don't pay bills at all. I'm so tired of it all. I told him I'm done and I'm going to my mom's. He gets mad and says I'm trying to keep our son from him and get child support. I told him I wasn't doing that but I'm not n leaving my son with him over night. I ft bad and decided to stay home so he can play with our son but no. He comes in and runs right into his bedroom and shuts the door. Then comes back out to use the bathroom. Our son is looking at him while he passed him up. He couldn't even say a word to him. Not even a hi son, nothing!. I'm just over it all. That's not a dad that's just a wanna be in public.
