Am I overreacting?

** sorry it’s a long one**

Before my husband and I got married the guy he initially asked to be his best man (his cousin) and his girlfriend hated me and put me on blast on Facebook. His girlfriend was calling me names (cunt, bitch, etc.) and saying I was nothing but rude to them. Long story short they don’t like me and they don’t like most of the family. They cut most everyone off my husband took them off of social media and all that. There was a text message exchanged just a few days prior to our wedding about how the cousin was getting treated for anxiety induced asthma I believe. My husband just told him he still loved him and hoped he would get the meds and help he needs to deal with things.

When all this went down the month or so before our wedding I was ready to call everything off. I disappeared for hours sobbing in my car with my dog. ( I cry writing this because all the emotions from that day are just rushing back)

Fast forward to now I’ve been getting pictures printed for a photo album/scrapbook I’m making of our wedding. I went on his phone and into Snapchat to send myself some of our pictures. And I decided to watch his friends snap stories because he’s got some of our family friends on there that I don’t have. Then the girlfriend comes up and I’m like instantly confused and he’s right next to me as I look at this. I’m like ‘hey when did you and so and so become friends again?’ And he’s like ‘oh she added me the other day’ and I said ‘Okay well can I delete her?’ And he said ‘I mean I was gonna wait to see if she posted anything before I deleted her’ and I said ‘well she did’ and he wanted to see and it wasn’t anything bad just a selfie and the. A picture of his cousin but in the past when he’s had her on there she has posted naked pictures of herself and of his cousin. He said back then that he didn’t want to see any of that on there. That’s why she was deleted in the first place.

Tonight it started this argument about how having her on there is the only way for him to see how his cousin is doing and it’s not that I don’t believe him. I know that is exactly why he would add her on there.

But initially I reacted out of anger and said “whatever you probably just want to see her naked” and he got upset as he should have because I know what I said was stupid but when I tried to explain how I felt rather than just leaving it at that. I told him to me it feels like a slap in the face to be friends with either one of them after the way that they have treated me and talked about me to my face and behind my back.

And he responded with how he didn’t want to be like everybody else holding a grudge against them. But he doesn’t seem to understand why it bothers me that he is friends with her again. He said “you don’t have to like them and they don’t have to like you but I’m not going to not talk to them because you guys don’t get along.”

But that’s not even it. I wish it was as easy as well I don’t like them so you can’t like them or be friends. It’s that they hurt me to the core and dragged my name through the dirt on Facebook for the whole world to see.

I just don’t know if I’m overreacting about how I feel but any insight would be appreciated.
