So for some background info my husband flew to Mexico to see his parents he hadn’t seen in many many years. His ex who I’m on a friendly basis with messages me to say he let her know he got there and wanted to know if he made it to his parents house. I was taken off guard by this and was quite unsettled by the fact that he even messaged her. I called him and said cut the contact off that she has no reason to know the details of this trip even tho they have a kid together. Do you think I overreacted?
