Alright guys...Should I break up with him? will choose BEST answer?

19 yr old female here...

Ok..to sum all the crap up in a short paragraph, Me and my boyfriend have been dating for almost a year now. Our Halloween plans did not work out because I had to go back to my hometown, so he took that opportunity to drive to Austin with a bunch of girls and one other guy to have fun (which I'm glad he found something to do).

Not much was going on in my hometown besides a few people got together to chill in the hot tub. I didn't go because I would be the only girl and felt that to be disrespectful to him. I couldn't go clubbing or anything either because he doesn't like the idea of me dancing with anyone else.

Now...I found out that not only did he go clubbing with all those girls...but he slept in the same bed with his female co-worker/friend. I found this highly innapropriate as I felt it was disrespectful to me and I got upset. He got irratated at the fact that I was upset because he felt nothing was wrong with it.

Today I told him I forgave him and I just wanted to move on with our relationship. he told me he didn't know what I was forgiving him for b/c he felt he had done nothing wrong. I told him that was fine but to just know that if he could to things like that, I could too. He told me that wouldn't be a smart thing to do and that I was being ridiculous.

so basically its okay for him to do those things but not me...

I'm so frustrated with this ordeal. I've talked to friends about it but was hoping for a few opinions that didn't know either of us and could look at the situation for face value.

Will choose BEST answer. Thanks so much in advance
