My mother-in-law is a control freak and pampers my husband to the level that it irritates me. I have seen my husband feeling embarrassed over a couple of times by her behaviour but he is not able to handle it. She often gets agitated when we lock our bedroom door while sleeping or otherwise to have sex.

She reasons that if something happens to her, we will not get to know because the door is locked. Once, after an intimate session with my husband, when I dressed myself up and opened the door, I found her standing too close to it. She was surprised and went away. This has happened a couple of times since then. I think she watches us making out through the keyhole. It is strange and freaky. Please help!
