My girlfriend is from another school and she has a very good friend from 11 grade, we met at the beginning of the 12 grade, the whole year I did not have anything against him because she needed a friend in that school, there weren't any normals girls so I just accepted it, now is the end of the lyceum and she is coming to University in my town. The whole year he tickeld her at least once a week and I don't accept any other guys to touch her, so I asked her to block him and not talk to him and she got mad on me, and said we will talk about this, what should I do? Should I accept their friendship? I do not talk to any girls and she is the only girl I talk and spend time with, am I asking to much from her to do the same and do not talk with other guys, especially with those who ticlke her?
