A.D.
My husband and I come from very different families. We both come from split families but my "parents" are my mom and grandma. I haven't see them as often as I would like since we moved but prior to that, I saw them daily on top of talking to them both on the phone several times a day. I literally called my grandma to just say Hi and I love you about thirty minutes before she died. I can tell you that my husband just sometimes hates the way our relationship functions but I think it's just because he doesn't understand it as he's never had that kind of a relationship. I get where your husband's coming from though. It's not a matter of not wanting to be with you or not cutting the apron strings, it's a matter of maintaining relationships and we all do that by how we previously functioned in them. Sure there is a spouse added into the mix and eventually there will be kids but it doesn't mean you just give up that portion of yourself. While I don't know all of the circumstances, perhaps he's just transitioning. Perhaps he's just missing home. It could be a number of things but your first few years of marriage are going to be all about a balancing act...learning more about each other, habits, wants, needs, desires, dreams; and you'll push boundaries and test the waters because that's how you'll learn to grow together as two individuals. I can tell you that if he's Jewish and you're not, you're going to put a gap between the two of you throwing around terms like "Jewish guilt" and "brainwashed." I can tell you that life is easier when you get along with the inlaws and you put aside your own judgments, which includes leaving his family out of bashing...particularly his mother. I can also say that I have teenage sister that I have to be there for at times and it's part of being the big brother or big sister. That label doesn't vanish with "I do."
My suggestion is this. You like the system as is...fine. YOU keep that system. Give your husband say a dinner night with his family and choose whether or not you want to go along. Just because you're married, does not mean you have to do every little thing together. Let him know your boundaries and use the time to get your nails done, go out with the girls or just have some "me" time (get it in now before the kids!!!!).
My other suggestion is that if you're not Jewish, learn more about it and use it to your advantage! That does mean not quoting the verse from Genesis because he'll laugh at you. For the record, it means to make babies with and become one via the baby. BUT, his roles as a Jewish male are to provide you with food, clothing and sex! That's right...sex is the woman's right and the man's obligation to provide without her asking!
Finally, I just wanted to say thank your lucky stars that you have someone that family means a lot to because that will transfer to you and the kids as well.
