This one's real self-explanatory. He's had a tryst with a much younger woman and is coming to the realization that he did something wrong by doing so. The girl comes to him unsatisfied with the younger guy she's with and is probably attracted by his being older and more experienced, more knowledgeable, etc. -- all the usual reasons why younger people hook up with people just a little too old for them. Now he's regretting what seems like an impulsive decision. This seems like it is more of a cathartic song for him, and that experience can probably be shared by anyone that's been with someone they shouldn't have been with.
