The end result of "sucking it up" all those years was that my inlaws seemed to like me reasonably well because my husband I allowed them to do whatever they wanted and say whatever they wanted to me, but I grew to dislike them very much. So in the end I was the angry one with bad feelings about the relationship and they were not angry at all. It doesn't have to be this way for you. Speak up for yourself and do what you need to do to take care of yourself.
