Errr.. wow..
First off, I'm not exactly sure what you're asking here?
What, specifically, is your question?
Is it:
My question for this thread is, since my boyfriend(husband to be)and I met online and we're going to meet in person and be together for 2 weeks, would they concider the time we spent talking online as having met?
You say you're going to meet in person for 2 weeks.. what exactly does that mean? Does that mean you're going over for 2 weeks for a VISIT, then returning back to the states, or does that mean you're going over for 2 weeks with the intent to marry and stay?
I'm not the best person to be speaking on this issue, as I don't know all the ins and outs of immigration, but to put it simply: No, immigration won't be sympathetic to the fact that you met online however long ago. They don't care if you've spent many hours and thousands of dollars on phone bills. They don't care that you've swapped e-mail pleasantries with his mom and dad. None of your online time spent together has any real bearing whatsoever on anything, as far as Immigration is concerned.
If you're only visiting, none of this is relevant anyway. Immigration wouldn't care, in the least, if you've spent many lovely hours together over the computer. In fact, I'd caution against even telling an Immigration Officer you're entering the country to meet the love of your life from the Internet.
If you're intending to meet up for 2 weeks, marry, and either a.) stay in the uk b.) return to the u.s. to sort paperwork and later return to the uk c.) both return and settle in the u.s. -- well, it's still irrelevant.
