My boyfriend's mom is getting into our relationship?

Gabriela • First time mom. 23. Due 06.26.17
My bf and I are having a baby. I am currently 11 weeks. His mother is very involved as is mine.
But my mother doesn't call him, and tell him shit. He has started to tell his mom when we argue. This morning we argued over the phone, because we currently don't live together, and his mother called me and spoke to me for 30 mins. Non stop talking and hardly letting me get a word in. 
She wasn't mean, but Jesus I already have a controlling mother. I don't need two. 
Like Jesus!! He use to complain in the past that my mom got into the relationship, but look at his. 
What the hell do I do? 
I don't need this stress.
