A bit of advise?

Farrah

So me and that guy like each others but he studies abroad and he comes only in vacations, he both are afraid to start a relation, I am not THAT ready cause I have been pretty hurt from my last relation which is his ex, so, I don't know what do I do in this situation, but I like him and my sister doesn't believe that i like him, cause she thinks I just wanna have a relation with any guy, do idk. Some advise please?
