The only time I lived with a woman I was not married to was great, very fair all around. We even lent each other decent sums of money and both of us paid it back as promptly as we said we would.She is still my friend. I disagree with brian’s fearful generalization.
Sdr’s thing is bunk too. I think it is more how you move your kids around, then whether or not you do it. Lots of real screw ups never left the hood.
I have no experience buying a house with a romantic interest who I was not married to… and I think I’d skip it. However, I think it could work.
