Mamas BOY

So recently my boyfriend has become a major Mamas Boy!!!! It’s starting to really bother me. Literally on the phone with her all day long. At work, when he’s home, alllll the time. And accuses me of ease dropping on his phone or not giving him space (FYI- it really is his Mom on the phone) if I say something. He get mad and says oh you have a problem with me talking to my Mom!!! He vents to Mom about me and everything that is going on, like no privacy. I know he talks about me because now she doesn’t respond to my text msgs. PETTY!! I’ve been with him for 9 years and this is all recent. He barely talked to his Mom before. He made me call to check on her because he didn’t want to deal with her. HELP!!!! Our relationship is struggling!!!
