Well where do I begin?

OK so my husband has been a really good boy lately and I wanted to do something nice for him, so I bought tickets to the MMA fights last Sat. I was able to keep it a secret until we were leaving the house to go there, which was fine with me.
We get there and everything is still going great. We had great seats. The fights were intense. But when we first sat down the order went my husband, my friends husband,my friend and then me. So to start there were two people between me and my husband and he didn't even care. Well I was going to make the best of it until I caught my husband staring at some tall toothpick of a girl. I asked my friend if she would trade places with him and she did. When he sat down I called him on his foul. He tried to deny it so I let it go thinking he would quit since he was now by me and he knew I was aware of it. Oh NO! the asshole still continued to look. I let it go.

Lets give a mental pic. She was about 5'8" and maybe 110 lbs. I am 5' even and about 175 lbs. I will never be like her. So when we get home my husband starts being a dick. Well I let him have it and he did apologized for doing it and said it was wrong of him, but how do I even start to get over that? Life sucks for me right now.

Well thanks for letting me vent.
