<human>: Can you give me the gist of the text in a nutshell?

So...I've been dating my girlfriend now for around 7 months, we have a great relationship, we haven't had sex yet because she wants to wait and I'm really supportive of her with that, all around everything is great.

She met this friend about the same time (5-6 months ago) at her work they slowly became friends and eventually in september they ended up in the same course at her university. 

Now just recently this guy has been texting her a lot about his girlfriend and the problems they have and he just broke up with her this past weekend, since then he has been texting her pretty much day and night which I was uncomfortable with but I didn't want to be a controlling boyfriend and tell her to stop.

Last night when I dropped her off he called her and told her that he really liked her but he didn't want to come between us (I know this is bullshit) and just thought she should know. No guy should be calling a girl to say he likes her when he knows and has met her boyfriend. She replied that she had to think about it and hung up...She just told me all this today over coffee.

Anyway, I think she shouldn't talk to this guy any more or at least she could have told him that she did not feel the same way when he called. She told me today that she loves me and will do what I want but I'm really not sure what would be appropriate? I know she will be faithful to me but I don't want her texting/hanging out with someone that wants to take her from me. Has anyone been in a similar position?
<bot>: Girlfriend's friend/coworker called her last night and told her he likes her, knowing she has a boyfriend and I have met him before. What do I do?
