So... I had a horrible sinking feeling when I saw an old conversation of my boyfriend's today. He was trying to find something to show me in his email when he opened this one up. It was a gmail chat that he'd had right before he met me. I only saw a little bit of it because he got nervous and shut it as soon as he realized what it was. Basically, he was bragging to some girl and flirting with her. Mostly about paying her for sex and anal sex. (No, he was obviously not going to actually pay her for sex... they were just kidding). I didn't say anything but I am so hurt! I think I'm being ridiculous and I feel dumb that this is bothering me. He hadn't met me at this time so he is totally within his rights to flirt with other people. I am just surprised because he never ever flirts online or in person with me. Even when we first met, he never flirted about sexual things with me. Is that bad?

Any advice would be helpful. I feel really stupid for being upset about this.
