So..can I be mad at him?

So, in 2015 my fiance went to a bachelor party 6 hours away from where we live for 3 days. My cousin is a mutual friend of him and the groom and also went. My fiance ignored me alot while he was away, and would get mad when I called. Before he left we agreed to no hanging out with other women and no titty bars because he had cheated earlier in the relationship and I didnt want the temptation there. He came home, reassured me nothing happened, I believed him, and our lives resumed at usual.

Fast forward to 2017, I went a girls trip with my Mom, sister, and cousin. He was up my ass texting me the entire time, freaking out because he knew I was going to Myrtle Beach, where my best childhood friend moved away to, who happens to be a guy. My friend got wind of me being there by pictures on FB and posted asking where I was staying and said he wanted to catch up. Mind you I'm here with my MOTHER and only family. My fiance called me yelling at me that I was not to meet him. (partially my fault that he was mad because I would joke that if cody hadnt moved away we probably would have gotten married one day) I ended up not meeting up with him and feeling terrible.

Well fast forward again to last weekend. I went to see my cousin who went on the bachelor trip, and he was talking about my fiance and how he was wild back in 2015. And that apparently he was flirting with the one girl that was staying on the same floor as them every day, and kept asking her to go to dinner with him but she turned him down. Then he proceeds to tell me my fiance paid $800 for a private back room at a strip club. I was beyond pissed. He waited 3 years to tell me about this.

I casually asked my fiance what all went on that trip and if he wants a similar bachelor trip "party". He said they just sat by the pool, went drinking, and fished the entire time. Then I asked if he went to a strip club, he said no. I asked if he tried to take a random chick out, again says no. I told him my cousin told me everything, and that I'm not sure about marrying him anymore.

He and his family think I cant be mad because this happened years ago. But the thing is he lied about it until he realized my cousin ratted him out. He ruined my trip with my family because a family friend wanted to catch up, but he tried to get with someone on his trip..

I mean what else could he have done while we've been together. He's obviously very good a keeping secrets.

I'm hurt and honestly just want to disappear.

Do I have the right?...
