I'm kind of in the same boat, it's been about 4 years since I've had an actual human being in my life outside of the family. I'm 29, had a distance skype deal or two, much like you, but it seems inevitable that something comes up in real life for them and they pull back without ever giving a real reason. While we're still stuck here. Feeling foolish for putting forth so much effort and not being met halfway. It's a bummer, but it gets easier. It gets harder.

Anyway, just wanted you to know you're not alone in being alone. And marriage and children aren't always something to envy. Think there are a ton of advantages to taking an alternative route in life. The fact that you're still functioning is something you should pat yourself on the back for... somebody deserving of you will pop up with time and as you learn what it is exactly you're looking and not looking for.
