I'm american on a work in the UK. I want to move home with my BF who is british. Need advice

I transfered to the UK 3.5 years ago where I now work and own a home, I would now like to return to the US along with my BF of two years. Can anyone guide me how to do this as I am having trouble getting info from the consulate...:-(

Thanks

first get yourself situated, and try to get a visa from uk. for your bf,then once thats cleared bring on down and either get him sponsered or get married, then start immi. papers
