Maybe look at a longer-range picture. How good a provider will he be for you and your children? If marriage and children are not in the picture, breaking up now or 10 years from now will happen.

Great relationships and "maintaining a relationship" are two entirely different things. Not to sound too harsh here but - you're sounding like you want to maintain the relationship like someone maintains an old car. "We can get 1000 miles out of those tires, probably 5 months out of the radiator and just ignore the leaks over the back passenger seat - it'll go away, probably."

I look back at my 45 years of life and was not very good at being selective and well-planned out for my relationships. The best one came along long after it should have and wasn't possible to maintain - so take care of yourself and determine if this guy is "the one" and if not, are you a great enough person to find who is really right for you? Of course you are - everyone deserves to give themselves someone who is their equal or better - who they rush home to after work rather than worry "did he get out of bed before lunch and clean up the dishes".
