If you decide to get married on one of your tourist visits to the UK that is ok also. After married you will then have to file for your right to remain. @First you will receive one for I think about 18 months, which will not allow you to work without a permit, or to be dependant on the government in any way. Then when that time is over you will re-aply for your unlimited right to remain, with no restrictions. I went through it all with no problems and you should not need an immigration attorney. Waste of money, keep it for your own enjoyment.
