Am I over reacting

So I’m 11 weeks pregnant

My birthday was yesterday and my boyfriend brought me McDonald’s breakfast and made me a cake with my son.

Then we went out to eat.

We got into a small argument about his mom being in the room while I give birth.

I laid down in bed in the dark.. he gave my son a bath and then said he’s going to play golf. On my birthday.

Thing is he never hangs out with anyone.

So he left.

I went to my moms an hour away because I didn’t want to be alone on my birthday. Birthdays have always been very hard for me. Somehow they always go wrong.

I texted him saying I’m going to my moms because I don’t want to be alone on my birthday.

After that I haven’t texted him since. He has texted a couple times since. Today he texted saying he’s going to play golf again.

I’m very hurt that he left me on my birthday.. alone

He told me “dont put that on me”

I’m really hurt and I don’t know if my feelings are valid right now..? :(
