You're too young for a boyfriend that's the problem.
Why do I get so bored with my relationships? Within a month or two of talking to a guy, I get bored. I've tried forcing myself to stay with them, but it just makes me unhappier. Any advice?
Don't rush into relationships. The problem is many people these days meet up & hookup without knowing each other. Why don't you just get to know people of the opposite sex for a month or two without actually dating anyone. Then when you find someone you really like and enjoy being around, then you date them.
