i came to the UK initially for work. but i'm staying for love. sure, i'd love to move back to the states in the future. i have 4 sisters, niece, nephew, cousins, etc. but my life is here. i found that i was driving myself & the boy INSANE with all the whatifs, grass is greener, etc. my sanity is much better now that i have mentally and financially committed myself to the UK (buying a house, joining clubs, etc).
ask me in 5 years and i may give you a different answer though!
