I have to be a little honest -- i'm confused. You're a little contradictory in your post. You've never been so sure of anything in your life, yet you don't know what to do? What are you sure of?

I agree with what the others said, honest and trust are key in any relationship. Without those, your foundation is shaky. Especially if you're going into a long distance relationship, without those two things along with communication, it could be nothing short of torture, unless you are both willing to work diligently to get past this...
