two weeks is far too soon to be even considering that this person is the one you can actually see being with long term. It is true that there is always some anxiety within new relationships but I feel that it's exacerbated by the fact that you are pushing so hard for a long term relationship with someone so fast. No wonder you're anxious. There are far too many questions to answer about you, him, the relationship and where it's going. You just can't know enough about him so it leaves a big question mark while you're trying to convince yourself that you truly see this person as a long term bf. Realistically we can say that you enjoy being with him right now.. beyond that, you can't know a thing yet.

relax, enjoy what you have now without pressure related to anything that points to long term for now.
