I just got married. We have been in an exclusive relationship for 3 years. There was an ex girlfriend that he had purchased a home with several years before me and they had called it quits. both names on the loan. they have texted and talked he states as friends while we have been together. Last November, I put my foot down and he told her that he was deleting her number. Recently on our wedding day she messages him on messenger and I just happened to see it stating that he had important mail at her house and by the way congrats. I messaged back as him to give it to a mutual friend and he would get it from them. she messaged him this morning stating she needed him to call her. he texted her and she is closing on a refi in May and he will need to sign off on the other paperwork...never mentioned the mail...he and I have been in a text argument all day over this. am I over reacting?
