I'm in College now and every choice is so big and so permanent....

I'm very young, and I've never had friends until 2 years ago. I'm really struggling with interpersonal relationships, and the major decisions which will decide my fate with that person.

I'm at a huge crossroad in my dating life, which will determine if I make this person my girlfriend or not.

It is also a decision I must make for myself, and cannot share details. So please, tell me how I should approach such difficult questions? How do I look at my problems and find a solution I can live with? I'm struggling here.
