<human>: Could you distill the essence of the text into 1-3 sentences?

Basically me and my girlfriend have recently gotten together and made it a serious relationship, despite having being in contact for several years and having sexual intimacy for a long period of time (over a year).
Anyway...
I happened to come across a text from a lad on her phone (I wasnt searching through her phone it was on the front screen) - I know of history between the two and after confronting her she said they are just friends now. She has proven this by letting me read all the correspondence between the two of them. She has told him she doesnt wish to lead him on and that they are just friends - HOWEVER - he hasnt understood this and keeps asking for them to meet up and for her to go round to his etc etc. I have discussed this with her and told her that isnt normal friendship behaviour and it is obvious he wants more but she is reluctant to tell him about me. I have suggested that they do not have to stop talking as i'm easy going so am more than happy for her to continue speaking to him as long as he is aware about me being her boyfriend and that they will not be more than friends. I totally trust my girlfriend not to let it progress further than a friendship but i do not trust his intentions. What should i do? Please help....
<bot>: Girlfriend won't tell her apparent "friend" she has a boyfriend in order to stop him indicating towards inapropriate things although she has told him they are nothing more than friends.
