You're in a tough situation. Your boyfriend is too. It comes down to the mother basically demanding the son choose between the two. It's drama as old as the hills, no woman will be good enough for her son. My wife and mother still don't get along. My wife is as laid back as it gets. She never loses her temper and rarely swears. My mother can get her pretty riled up though. I stand by my wife. My mother learned long ago not to test me because she'll lose. I love my mom but when it comes to my family it's all or none.
His mother is one of those had 5 children to 5 different men, had them all taken by the state, can't stay out of jail, lives motel to motel until she gets caught sucking dick for room money and gets thrown out kind of mothers. Yet still somehow demands the respect of the children she didn't even raise and tortures them, pretty much.. well, the ones who are over 18.. 3 are still under 18 and are completely gone. My boyfriends younger brother is 22 and has been in jail for a few months now, and my boyfriend is currently and finally clean of the meth she got him hooked on that he's struggled with for many years and went to prison for.. yeah. She's really not a good friend of mine ha
