Am I overreacting?

I have been with my wife going on 17 years. We have a family together. We have had some ups and downs in the relationship. I do trust she would never cheat on me. Maybe other things but not this.

Background to the story. Her ex boyfriend messaged her one night that he missed her. That he was glad she was his first. That if he could he would love to have one last goodbye with her. To me that’s disrespectful to her, to me and to our relationship that he would message that.

I asked her to block him. She didn’t. She told me I wasn’t going to control who she is friends with on FB. And that it would just give him more power. Which I explained I feel uncomfortable with him having open DMs and watching our life on FB.

Months go by and we go out in town one night. Her best friend decided to snap chat this same ex. He noticed my lady was as with. He was calling them sexy and how they looked so good. The dude ended up showing up 30 minutes later. During that time her best friend kept asking me how I felt. What I was going to do if she showed up. Blah blah blah. Which being mature adult I said nothing. He doesn’t matter to me. But clearly he doesn’t care about me or this relationship. And weirdly it seems like the best friend doesn’t either. Anyways we have a big argument over that whole night. I expressed feelings about her friend bringing her ex to the bar when clearly he was being inappropriate. I can’t control everything. But I didn’t appreciate him showing up and her friend trying to hype me up and then for this dude to show up. What the fuck?

Fast forward a week now. I find out my lady messaged her ex the next morning after the bar. Saying how it was nice to see him and to get caught up. And how she was sorry we left right away. We didn’t leave cus of me we left because her best friend was falling over everywhere and we had to take her home. Either way she messaged him. I did ask if he ever messaged her back after that night and she didn’t say anything about it.

I wasn’t perfect in this. I did decide to look at her messages myself and invade privacy but that’s when I seen the messages to him. To me that is pure disrespect. I explained to her I trusted her but to message the guy I wanted blocked? Who said those things to you? Disrespecting me? And you thought it was a good idea to message him? About how nice it was to see him and to apologize to him? I told her men who message gross things and get a pleasant response back thinks that a door open to keep messaging. I told her he now knows you read those messages and still were nice to respond back to him. To me she wasn’t considering my feelings and didn’t think about me and how I would react. I am hurt she would even message him.

This may be petty but I believe in relationship respect and believe if a woman had messaged me those things and my wife wanted her blocked. Easy choice. Respect my wife and my relationship. She thinks she was just being nice and friendly. Which she is. I don’t think she would ever do anything. But to me it’s the principle.

Am I over blowing this situation? Should I not be this upset? I just don’t know what to do anymore. We have fights about everything and now this. Is it time to call it?
