You don't HAVE to drop your relationship with her family. Sometimes LBS have a fantasy the WAS's family will choose the LBS *over* the WAS long-term. That's rare. What's not rare is some people who had good relationships with their ex-inlaws maintain them through a divorce. You are no longer their daughter's husband, but you are still bound to them as their grandchildren's father.
My XGF is invited to any ex-inlaw family gatherings where XH is not invited. Besides maintaining that relationship, the ex-inlaws get more time with her D and S.
