Quoting Spencer Pratt:" That would make me a hypocrite, I have 3 children with 2 men, oldest two with one, youngest with another. ... [snip!] ... another. However there is a 10yr gap between my middle child and my youngest. For me it would depend on the circumstances. "
I think as a woman, I'd just have a hard time dating a guy and being the 3rd "baby mama".
A guy I dated had 2 kids with one woman, had another by a 18 year old girl fresh out of high school, and was talking about wanting one with me. It just turned me off. Had he had been like, the love of my life, maybe it wouldn't have bothered me, ya know?
But he was also exactly what you described.. Lol.
