A big problem

The problem is that I have to get a visa to come back to England again. It's not necessary to get a visa but if I visit England many times as a tourist, it will be getting hard to get a visa in the end. That's Britain!! I've been searching about sorts of marriage visas and how to get them but it has made me fed up because it is all very complicated and I need lots of documents about me and my boyfriend and possibly an interview as well. If I do all things, I don't know whether I will get it and how long it takes. As it is of anything, starting new things are hard. Anyway I must overcome it otherwise there will not be an opportunity to vist England again.
