Hi all,

I've been dating my girlfriend for just over a year now.  Usually, she's a pretty great partner, and we have a healthy relationship in which we both try to be open and trusting with each other.

Recently, something happened that made me have some doubts.  There's a mutual friend we have that she finds very attractive (and she's told me as such).  I haven't thought much of it - both of us find others attractive and that's fine.  However, recently, we were out with him and she started gushing about how attractive he was.  Another time, we were with him and others again, and she told me that she felt disappointed that she didn't look attractive enough for him.

I've asked her about it but she was pretty dismissive, saying it was nothing.  Am I right to be a little worried?
<bot>: Girlfriend told me she didn't feel attractive enough in front of a mutual friend that she's said she finds very hot; am I right to be worried?
