Legend auld boy, how's things?
I think it depends on the lady or man in question, how much support they get from the absent parent and from friends and family in the babysitting stakes etc. Doesn't necessarily mean goods would be damaged to me, unless the afterbirth and stuff is still hingin oot!
I would have to think a bit longer about it before getting involved in anything longerterm to make sure that we were going to be stable as the kids would be upset too if you break up.
