Do you have kids ,Uberman ?
che it sounds like it worked out for you
so far. But if you do break up and she wants a divorce it's your money to her and the kid for years upon years, while she lives the high life you will be struggling to survive, why, because that is the way the law is setup as of now.
Sounds like your the kind of guy who wants other people to be in your position, wife and kids, many people are perfectly and more content without those responsibilities.
