Hi,
I think, you talk to your husband and tell him in detail about the whole situation. Some women think that by letting go of the control, they will lose their power. Perhaps, she thinks the same way. I think, if your husband understands, ell and good, but if he doesn't then you do one thing. Enrol yourself in some class or activity, and I am pretty sure when your MIL will see you going out, she will have 100 errands that she would want you to do. Because then she would know you have to go somewhere and be on time, so she will make sure, she has work ready for you and then she would sulk also if you won't do anything unlike now.
