<human>: I am a 23 y/o female and my boyfriend is a 24 y/o male. We have been together for one year.

A few months ago I was snooping on his Facebook messages and saw he had messaged a girl from his work. It was a pretty casual, friendly conversation, with maybe some slight innocent flirting (he said to her at one point "it's a bummer we don't work together more often!" for example). She was also very beautiful, so I freaked out. I am beautiful too but I have low self-esteem, so I completely thought the worst, as in he contacted her because he was into her.

So I discussed it with him and apologized for snooping. He was very understanding and told me she was only 17, so he definitely didn't see her that way, and that it doesn't matter at all because he loves me and would never cheat on me or leave me for someone else. He said at that time he messaged her, she was having "family drama" and had been talking to him about it at work. He saw she was online and decided to see how she was doing and cheer her up.

I guess my concern still is that is it normal for guys in relationships to talk to their attractive coworkers outside of work? I personally don't use instant messaging so I find it hard to relate. My boyfriend is an extremely friendly person, and I know for a fact he is friendly with everyone at work, so maybe he is just the same way online? I just can't seem to get passed how pretty she is and think he was messaging her because he wanted to talk to a pretty girl:( He had text messaged and talked to this other girl from his work in the past but I never batted an eye because she wasn't prettier than me in my opinion. The 17 year old on the other hand, is very pretty. I KNOW how petty and dumb this sounds. I'm actually working with a therapist to combat these thoughts. I just want someone to tell me that what he did was totally innocent and normal.

Give me the gist of the text in a nutshell
<bot>: Boyfriend had a Facebook conversation with an attractive 17 year old girl from his work. It was innocent, but I'm still freaking out. Is it normal for people in relationships to chat with their coworkers on Facebook?
