Hello! Your story is rather similar to my own. Studied abroad (from a university in Ohio, as well), met British guy, liked British guy, came back for Masters degree, married British guy, moved to UK on a spousal visa.
Doing a Masters degree here is probably your easiest way of getting over her at this point and time, especially if you were already planning to do one in the UK. It can be expensive but, once you are here, you have the chance to switch from a Tier 4 to a Tier 2 or Spousal visa. It's been a few years since I have done either visa but neither were so complicated to need a lawyer unless you have a history of overstays, criminal record, etc. This forum is extremely helpful for any questions that you may have. Have a read-through of the gov.uk site so that you have an idea of the rules and all that. Good luck!
