Lolawar-it is awesome that H's family is supporting you and has said they will not allow OW in their house. My in-laws are supportive, but are in denial about the EA, and have even gone on a trip with OW.
Nicole - I would agree with the others. Call your MIL and ask what she would have you do, but do not bring up H unless she asks and be careful what you say because she is his mother and although she may not agree with what he is doing, she still loves him so tread cautiously, but answer questions if asked and don't keep MIL out of your life.
