Sad😔

I think my boyfriend is embarrassed of me and doesn’t like me. Every time he says that he’s going out I offer to join and he makes a million excuses as to why I shouldn’t go with him. Not just that but he never posts me on social media. What hurt me the most is that I gave birth 5 weeks ago to our first baby and on Mother’s Day he posted a picture of his mother on Snapchat with “happy Mother’s Day” written and didn’t do the same for me. I’ve asked him to give me massages as an act of intimacy since we can’t have sex but he has not given me one even though I recently gave birth and would appreciate a massage. He now sleeps at the bottom of the bed and is out most of the day. I have the baby all day and night which I don’t mind because I love our son but I just wish that he were more involved and would help a little more at night. Right now it’s 12 midnight and he still hasn’t brought himself to bed. I just want to cry. When I try to talk to him, he sees nothing wrong with his actions and switches things on me and says that I act like an animal and that I bring negative energy. Every time we argue he also says that I have no ambition when I graduated college 2 weeks after giving birth and I’m only 21. I feel so alone, I have no friends since I’m always home and super shy. My self esteem has dropped significantly the only thing that makes me feel happy and whole is my baby😔
