I agree with the other posts here--I think things will change once you go home
You and Tim will have a lot of time to reflect on things now that you've spent some time together, almost living together in some ways. I think for me and Steve things changed after my first visit, because I had actually lived in his house for 6 weeks, and he realized just how much he was missing by not having me there.
Normally he doesn't talk about 'feelings', but last night he said he misses being able to turn to me in bed and just talk about something. Now he has to leave it till the next day when he can get on MSN
So, who knows what will change between now and when Tim comes to visit next? It'll give you two a chance to figure things out, and to see if it was really meant to be, and I think it might be
I think in a lot of LDR, it eventually gets to the point where marriage is almost the next logical step, like it is with a lot of other couples in more conventional relationships; with me and Steve, we've been together for three years already, and I'd like to think in some small way that if I was British we'd be getting married anyway (yeah, I still worry that I'm forcing him into something, but I have to remind myself that he's a bit, 38 yr old boy).
I swear, I will seriously be over the moon when I get my hands on the visa. I won't be able to genuinely relax until I have it, and I *know* can move on
Time heals all, in a way--it took me a couple weeks to do it, but I slowly adjusted to life in the US even though I didn't really want to be back here in some ways. Well, at first I was *thrilled* to be home, mainly because I was sick on the second flight, after 20 hours of travel with only a cat nap in the terminal, so being able to sleep in any bed was great
I envy you in a small way, I kick myself for not living on the east coast, I really hate me some 24+ hour transit times.
But it's very frustrating ultimately, I sometimes tell myself it's not fair. But it's also good to have that trip to look forward to next, it's something tangible and concrete to hang onto. And it takes a lot of planning to show a Brit around the US I find, so that's something to think about for the next couple of months
