The one thing I thought that would never happen to me again happened. My husband of 7 years ttc for 3 of those slept with a 21 yr old from his work and lived with her for a month. I thought he was staying with family bc they needed help. I’m crushed idk what to do or how to get past it. I messaged her she knew about me and mocked me. So that’s that. I’m lost and feel numb

Just to clarify I was cheated on in a previous relationship. Not this one this is the first time with my husband.
