ok guys, sometimes people do need to move away from parents, I have seen situations. (therapy would be befeficial)
I also have seen where a spose is keeping close with ONE side of the family, and yes, it is unhealthy, andin a long run, wveryone will lose out.
If a spouse keeps her away from her family, it may be a warning sign. you cant package all family as one (parents and sibs) and therefore cut off from everyone.
She may be not confident enough, afraid to see it or to challange it.
maybe developing a relationship with him (you and husband, as a couple), arrange a get away together – try to create some friendship so he gets to know how wonderful you are.
If all fails, talk to a smart rav. it is something that needs work, no need to giver her up. Good luck!
