Did Lincoln Regret Marrying Mary?

[RJNorton]

I think Lincoln loved both his wife and sons very much. What are the major arguments that he regretted marrying Mary? I know Michael Burlingame lists a series of "incidents" noted by neighbors in Springfield, but personally I have thought Abraham had a "that's Mary" attitude toward these rather than serious regret. I don't think he was the easiest person to be married to; personally I don't think their arguments are cut-and-dried either way. Each person loved the other one, and they had their differences like most married people do.
