Ok I know this isnt the rite fourm to post it on but im confused and didn't know where else to put it.

well im 14 and I have been talking to this girl on the internet she goes to my school and we have been talking over a year.
The problem is when she say's other guys are nice I get really annoyed and I hate it when she talks to other people and its weard. Also I just see her and it makes me happy ?
