I understand that you must feel you are dependent on your mother. I'm in a similar position. However, you need to realise that you're an adult now. Your mother can't STOP you from going to see your boyfriend a few states over. It's only a few states over!

It's the old saying - where there's a will, there's a way. If you REALLY wanted to see your boyfriend, you wouldn't be sitting here, you'd be going out and doing it the first chance you got. It sounds like you've already missed a chance or two. Why is that? Is it because of these circumstances, or is that just what you're telling yourself? You just said that the relationship is really hard on you. Is this forming some kind of block in the way of advancing the relationship?

I hate to go all psychologist on people, but I'm speaking from personal experience. If you talk endlessly about wanting to meet up with your LDR boyfriend but never really make a move to, there's some problem there outside of physical circumstances. At least, from my experience. I could be wrong.

Anyway, hopefully that might give you a little extra to think about.
