Mamas Boy

I think my boyfriend is a mamas boy...the reason why I say that is because he can never say no to his mom and it drives me nuts. His mom would interrupted our dates like “I need milk or I need you to go get pizza please”. Back in high school, she would literally compete with me who went to the most football games. We try to go on a vacation recently and his mom said “ don’t think it’s a good time” and he goes along with it. He is 20 years old, off to college (we both are) I told him he I can pick you up from the airport and he wanted me to but when he told his mom and his mom said no I want to pick you up. He told me his mom responses and he went along with it and he pisses me off like really how old are you ? He has a problem with saying No to her!!!she pulled the pitty me “im sad” “I’m lonely” “I need love” oh and P.S she hates my guts because I take good care of him. Is it just me ?? Am I overreacting?? How do I handle his mom?? Should I leave him ??
