5L DIDN'T HEAR IT FROM ME - MAMA'S BOY

You didn't hear it from me, but… My Girlfriend calls me a Mama’s boy and she has given me an ultimatum... We have been together for 5 years and my mom has always been part of the relationship. She was even involved in some of our big decisions like where we moved, how we furnished our place, and so on.  The other day, we were in the middle of a DMC and i chose to pick up my mom’s phone call because I never miss her calls, no matter what.  My partner said its eitherI start prioritsing her over my mom, or she is going to leave.
