<human>: Give me the gist of the text in a nutshell

He messages her on facebook frequently (sometimes double or triple messaging) saying how wonderful she is, saying he wants to see her smile, saying he loves her, etc. He also tries to do favors and nice things like fixing household items, making her dinner, lending her stuff, etc. Recently he spent three hours making her dinner, she was unavailable (spending time with me) and he later messaged her saying she's a disappointment as a friend. 

I've been dating this girl for two months. This other guy has been friends with her for like three years. I've met him once and he was surly and quiet toward me. I'm not especially worried because I feel capable/desirable in all facets. This guy, at a minimum, has personal issues. Still, he's good at certain other things in his life and seems like he could be fun to hang out with.

The other guy is friends with her roommate and my girlfriend also wants to keep him as her friend. 

My girlfriend has been open about it, told me the situation, and shown me the messages he sends to her. 

Like I said, I'm not especially bothered, but I'd rather she didn't hang out with him. He doesn't respect her relationship and is actively still seeking her.

I've told her how I feel and she agrees. She says she's not interested and really wishes he wouldn't behave this way (excessive favors and being called a disappointment when she doesn't accept). 

So... should I communicate to the guy myself? I feel disrespected and slightly uneasy with her keeping him on as a friend.
