Hey, connerlevismom, does your DH happen to be an only son? These kinds of issues with mothers and their 'only son's is more common than one might think. If I remember correctly, I actually read once where this was a recognized issue, and there is a name for it!!!
My DH is an only son, and while there have not been the issues that you have described, his parents were WAY over-involved and overly vested in their son. We had to draw some boundraries, big time. And, even with that, my DH has still been way more involved with his parents than most other men.
OP: I don't think that anyone is saying to cut off ties and not see your MIL. Of course you will continue to see her! HOWEVER, what we are trying to say is that if you do not take heed, and create some boundaries (with your DH at the forefront) and learn to stop enabling her behaviours, it COULD very quicky become a huge issue, to the point where irreparable damage is done to your relationship. As long is your husband is in your corner, and is seeking some more normal and acceptable boundaries with his mom, then all is good!!!!
If not, you will find out that you do not have an inlaw problem, you have a marriage problem. Surely this is not the case!
