"Take me to the movies"

My boyfriend yesterday after getting off work went to his friend's new house for a BBQ. He drank beer and had a good time. I stayed home because I'm 38+2 in my pregnancy and he doesn't invite me anymore to leave the house and go with him to see his friends although I could have just sat there and ate all the food. When he left yesterday I asked him to take me to see finding dory! We both loved finding nemo so I think it would be fun to go together. I set up all his Father's Day stuff on the counter today, so would it be cool if I asked him to take me tonight when he gets off work or tomorrow on his day off? He spent $20 on his friends buying them beer and chips so I think he can spend that on me too.
