Why Do I Feel Over Protective???

I all of a sudden feel really over protective, of my girlfriend.......
Today we went to town (Me and my girlfriend). Shopping for a few hours then we went back to hers and watched a DVD layed down on bed in her room........ All the way through the film we were kissing, holding her close to me. It felt amazing I told her on several occasions "I love you". I went home having had one of the best days of my life, We talked on msn for a few hours, But then this guy her friend that he met on holiday in the Dominican Republic added me on msn he started callin me **** im like dude i dont even know you!!!!
He eventually stopped then i asked my girlfriend what was up with him. I also said joking at the time "anyone would think he was jealous...........lol Then she sent back "look at his bebo page" (Bebo is similar to myspace and facebook) On his bebo page it says "YA FINK PEOPLE LYK YA N THT BUT WEN SUM1 ELSE CUMS THEY JUST ***** LEAVE YA N DUNT GIV A **** BOUT OWT ELSE AY ASH".............

That was copy n pasted fro his bebo^^^.
What i am trying to say is he definetly her and she is going to see him soon and she likes him (i dont know if its more than a mate or not) He lives a long way frm me and my girlfriend. Btw I am 14 my girlfriend is 15.
Am i right to be parranoyed???
Has anyone been in a similar situation???

Um, I'm not sure what went down. Was he calling you on the phone? Or calling you a name over msn? Did you girlfriend meet him, or was it a friend of hers that met him? And, while that may be exactly what he typed on Bebo, I have no idea what he's trying to say...

i have no clue what that last part says or reads!

I think that you should drop dis ***** like a 3-foot-putt
