<human>: Provide a brief overview of the text.

So my girlfriend knows this guy and it's pretty obvious he's had a thing for her for about a year now. He does sweet things for her like get her flowers on valentines day (this was before we started dating) and he's pretty flirty in conversation. I feel like I have a good sense of what's going on because I've definitely been "friend zoned" before and everything about this seems all too familiar.

I don't necessarily feel threatened...I just feel bad.  I don't really even know the guy so it's not like I really ever talk to him, and he's never done anything drastic enough for the situation to be addressed by anyone.

I can't blame my girlfriend either...I know a lot of times the girl gets blamed for leading the guy on in these situations, but really if she paid any less attention to him, she'd be flat out ignoring him.  And like I said earlier, he hasn't done anything drastic enough to give her reason to do that.  I think she feels it would be presumptuous to assume he wants her, and doesn't want to lose him as a friend either.

So what (if anything) should I do?  Honestly, I do feel a tiny bit weird about his feelings for her. He lives on the other side of the country though, so it's hard to even feel threatened.  The reality is, I can all too easily put myself in his shoes because I've been there before, and the only thing that saved me from the heartache was to realize that I'm wasting valuable time, effort, thought and feelings waiting for a ship that won't set sail.
<bot>: My girlfriend has a dude friend-zoned and I feel weird/bad for the guy...is there anything I can even do?
