First, do you see any potential problems with this statement?
..If we stay together AFTER college and things are long-term for a few YEARS (I am imagining he will be living at home because SHE doesn't like the idea of him moving away)... Do you really want to be stuck with an overbearing & controlling woman who will
continue to dominate every aspect of YOUR relationship that she possibly can for years?!?! Even
after he graduates college & presumably gets a job & can support himself?
If so....please think again.
Hard.
I'm in very much the same position with my fiance--we've been together for nearly 6 years...and his mom has NEVER changed. In fact, she's gotten worse. The only reason I've stuck around this long is because BOTH my fiance and I agree that he needs to move out once he's done with school and has a job. (He'll be moving out in August, by the way).
The amount of stress an overbearing & controlling mom has on a relationship cannot be overestimated--and the effects are compounded even more when one of the parties is unable to get distance because they still live at home.
As parents, I feel one of the main responsibilties is to raise a child to become an independent adult...this woman is determined to keep him an eternal child--and YOU'RE prepared to allow it.
For his own sake, he needs to move out as soon as he's able. He will never get a chance to grow up if he's contantly having to kowtow to mommy. He will always be her little boy, and not a man in his own right. She will never respect him as an adult if he's content to be treated as a kid. Even though the transition will probably strain their relationship, moving out & establishing your independence as an adult is a period of adjustment that EVERY parent and child in a healthy relationship have to go through.
For the sake of your relationship, he needs to move out, because she will never stop infering to the extent that she is as long as he's under her roof. She will never let up, she will never quit, and the best thing you can possibly do is limit the amount of control that she has over her ADULT son's actions--the most important and vital step will be having him
move out. Talk with him, and see what his plans are for after graduation...he might already be thinking of getting his own place.
If he is, that's most of the battle already. He has to WANT his independence, you can't push him into it...and if he doesn't want to get a little space from mommy,
please think very carefully over whether or not you're willing to live your life playing second fiddle to his mom--with YOU cast in the role as the other woman.
Try not to think of it as a confrontation. This is just a discussion over what your plans are...both individually and as a couple. Talk with each other, and listen to what both of you have to say. For the sake of establishing his own identity as an adult & achieving indepenence, moving out will help, and for the betterment of your relationship, having his own place where his mom doesn't dictate your relationship can help, too. It's all about setting healthy boundaries that you both can live with, and it's not impossible.
Best of luck to both of you!
