RYL Forums - relationship advice..?

I'm not really sure if this is the right place to put this, but I figured I'd try anyhow.

I'm having a bit of trouble with relationship things..
Basically I was dating someone for around a month while they were at Uni, and that was fine and good, brought up some problems but overall was positive. Since they went home for summer I've realised how I feel/think about them has turned predominately negative, and in turn we've only exchanged words over msn every 5 days or so and nothing very meaningfull. In the meantime, I've realised I've started to fall for someone else.

the problem is, that the person I'm supposedly dating doesnt "get" me. They don't understand me at all, whereas person X does. However, person X lives 100+ miles away and I don't think is interested in me romantically. We have been texting each other daily though and have deep and meaningful conversations, where I feel I have actually emotionally connected to them, which hasnt happened to me for way over a yr and ahalf.

I'm reluctant to 'dump' the person I've been dating purely for selfish reasons, theyre the only person offlijne who has looked at me twice in about 2 yrs, and I did enjoy the company while they were local. Now however I find myself cursing them as they are creating a restriction if anything were to develop with person X, which I'm about 90% sure it won't.

I'm pretty sure person X doesnt think of me in 'that' way, and would possibly be surprised/possibly insulted? if i let on I would like to be closer. But the contrast has made me realise that the person I'm dating i have little in common with and no attachment to.

I don't know what to do. I guess the sensible thing would be to talk to both of them? I don't know. I can't figure out if i'm only keeping around the first person because i'm lonely and liked the attention, or if there is more but because they are now 200 miles away its like 'out of sight, out of mind' whereas i've never had the closeness of physicalities with person X.. though theyre never far from my mind..

Any idea's or advice at all? I don't know what I'm asking for.. I just feel so weird and twisty over it all its making me uncomfortable but i dont know what to do, if anything, for the best.
