Not really. Divorce only becomes more difficult than just leaving if you want some of that community property. And, if that's the case, its no more or less difficult than ending a partnership, civil union, or business.

And, what's the difference between a wife staying with you to avoid the extra hassle of tryna get half and a gf staying with you because she has nowhere to go?
