My brother-in-law (who is also a long-time family friend of my mom's, and is my husband's best friend) recently found out his wife has been hanging out again with a man she had an affair with. Since then, he's started coming on to me, sending me dirty text messages and pictures, and trying to get me to hook up with him. The more I say no, or stop, the more aggressive he gets with it. I'm afraid to say anything to anyone, because I don't want to mess up things with my husband and him, or between him and my family, but I don't know what to do. I live down the street from him and we're both stay-at-home parents, so we see each other all the time, and I can't really just avoid him. Tomorrow he's watching our baby while I take my older daughter to the dentist, and now he's sending me texts like, "This is going to happen when you get back to pick the baby up," and "I'm not asking, I'm telling" and that kind of crap. It's just getting to the point where I can't just deal with it, and it makes me uncomfortable to be keeping a secret like that from my husband. What would you do?
