I'm so confused!

Am I falling in love with someone who is not here?
Am I going to consider long distance relationship?

It would be easy to say no..... but this guy is really nice......

But what still remains are all my insecurities about myself..... he can say the nicest thing but I'll have nothing to say in return because 1) I don't know about where I'm gonna end up staying 2) I really really really don't want to consider having a long distance relationship 3) I keep feeling like he's going to get bored of me after a few months.... or I may get bored of him...... I don't know what to think......

What I do know is that I really like him..... he is so caring!!!!! And I'm scared that I may lose that...... so the walls are way up..... way high......
