Great question. The answer isn’t pretty. Biologically, men are programmed to travel and spread their seed. Women, biologically, are programmed to nest. See the problem?
The trick for both men and women is to be with someone who has mutual goals at the same time. If a man knows that he’s going to want to settle down at one point, and he meets a woman who is too good to let get away, he’s going to cut a deal with himself. He’s going to give up that wild life in order to snare the one he doesn’t want to let get away.
If a man just isn’t ready to settle or hasn’t met a woman so great he’s willing to cut that deal with himself, then he’ll go on with his bad boy ways (in your case) — or whatever ways he has that work for him.
Being with a woman in a long term monogamous relationship requires a balancing act where each person in the relationship is true to themselves and to each other. Trust me — this is never a smooth road for very long because men and women are so different, but with maturity and understanding of both men and women by both men and women, it can be a wonderful adventure. But it requires women to understand how wild men are by nature, and to know that in order to keep their man happy, they’re going to have to work to keep him intrigued and keep the home fires burning in every room — but especially the bedroom. Because, after all, isn’t that what got you to step off your Harley for a woman in the first place?
