<human>: First of all, apologies if this is hard to read and for any errors as this was typed on my phone.

My boyfriend and I have been together for 3 years, we have lived together for approx 2 years 4 months. I ended up moving cities to live with him, and together we have lived in a few places over the duration of our relationship while he finished his degree/masters. 

Fast forward a couple of years and he graduated 3 weeks ago and has just secured a great job down in London in the same field he was studying. We have always wanted to live in London as it seems like a good fit for us, however it is extremely expensive, I'm sure it's on the same level at New York etc. He will be earning approximately £600/$940 more than I will. I will most likely be working in retail to start off with so I will be on a low wage. 

My question is how should we split finances? We're used to sharing all money by the way. Do you think he should pay more rent or not? My whole monthly wage will be about the same as a months rent. I don't know how this should go as it will be our first time working properly and fully paying our rent etc. by ourselves. Even with his wage it's still just a starting out position and money will be quite tight due to rent prices in London but we feel it's worth it. He said he thinks he should get a bit more spending money, which is perfectly fine given he has earned it but it will probably make things really really tight for me. Quite frankly I'm absolutely terrified about the money situation because it is so expensive to live down there!

Sorry if that was a bit all over the place, I hope it makes sense and we could really do with some help and opinions on what you would do?

Can you give me the gist of the text in a nutshell?
<bot>: Moving to very expensive city with boyfriend for his new job, I'm concerned about money. He will earn more money than I, how do we work out how to split finances such as rent or what's fair?
