Husband going to another women's house who's known for sleeping with married men

Before anyone says anything, the problem isn't necessarily that I don't trust my husband. We've just been going through a rough patch for the last few years. I'm in therapy because I have not been the best wife and mother. I've acted selflessly and taken my trauma out on my family. I had an emotional affair 5 years ago with my daughters best friends father and my husband almost left me but he decided to work it out. My daughter still holds resentment to me since what I did made her friends mom ban her best friend from talking to anyone in our family and she lost her best friend. I made so many mistakes and I'm trying to fix them but I'm worried because of how my husband has been acting towards me lately that he's going to revenge cheat. We've had more issues and he moved to sleep in the guest room. We start marriage counseling next week. My husband works at an alternative school and they have multiple parent teacher conferences throughout the year. 4x a year and have their first home visit of the year next week. One women is known for sleeping with married men. She actually made a Facebook group for women having affairs where they can talk about being with married men. My husband has to go to the home for a visit for one of his students. I don't want him too. Especially when our marriage is Shakey. The last thing I want is him to be tempted.
