When I was 16, I "long distanced" dated a girl, we would talk all hours of the day, cam, everything. I spilled info I'd never say to anyone to her, and it was great, besides physical contact.
Once she turned 18 it was like she got bored of me. Everything faded away and because there was no physical contact it was like fhaving a school-crush on someone, but knowing all about them, but couldn't even give a kiss.
I had several chance to meet her, but when the time arouse something always "came up"
I'm over it now, I just feel it was wasted time as when we talk to check up on each other, once and a while, it's always empty.
My experience, long-distanced relationships are NOT worth the hassle.
