Can I get a 1 year UK long term visitor visa? [closed]

My boyfriend and I are US citizens. He will be attending a 13 month long graduate program in the UK. We want to partake in this adventure together. Would I be able to get a long term visitor visa for a year? On the UK website I have only noticed that "long term" visas start at 2 years. I don't need 2 years. I also don't really want to spend money on a student visa because I have my nursing license here in the states and I am taking my BSN online while hopefully over there. I also have had no luck with finding a sponsor due to the fact that I can not apply for jobs on the shortage list like "nursing" because my license does not transfer. So far my only option is to head over there for a 6 month visit in hopes to find a visa for another 6 months after returning home (or even more stressful.. try an do another 6 month visit with the risk of being refused) I think I already know the answer... Just would love to have some tips, input or suggestions.

Thank you in advance!!!!
