Like the others, I have my doubts that you're still reading this, but here goes:
Let me tell you something about long distance relationships, and it's something that almost every person here could tell you. Long distance relationships are hard. My wife and I met online back in 1999. Between March of 1999 when we became a couple and December of 2001 when I moved to the US for the first time, we spent a grand total of 7 weeks actually physically together. 7 weeks together and 135 weeks apart.
It would have been easy, really easy, for either of us to walk away. The only thing keeping us together was how much we loved each other and how willing we were to work on this. We hated every minute we spent apart, and cherished every brief gone-too-soon visit.
There's an attraction in the different, in the unusual accent, the different cultural background. It's easy to think of someone from wherever you're not as being more exciting and special because they're from somewhere else. It's easy for a little while, anyway. if you're in this just for the delight of an englishman being Prince Charming from the land of Happily Ever After, before long, one of two things will happen. You could start to hate being apart so much that the presence of nearby, available people will turn your head. Alternatively, you could meet your idealized paramour and realize that (and I hate to break this to you) British guys are just guys. They fart in bed. They leave the toilet seat up. We're just like other guys, only much more inconveniently located.
If you really and truly love someone, and they love you back, you can overcome this. It's not easy, and you will hate every second you spend apart, but it's possible. it's also I should point out bloody expensive. Every vacation you get will be spent going to see them. Your phone bill will be massive unless you have Skype. When you finally get to the point of getting a visa (or he gets one to come to the states), it will take months and cost you a fortune.
If it's just a crush, or if he doesn't share your feelings, take my advice and spare yourself the years, the money and the heartache.
