So the age old question of committed, long term relationship vs. dating and playing the field.
The problem is chemistry.
Studies have shown that the way we feel when we're meeting new attractive women for the first time, or charging into new relationship territory, there are chemicals released in the brain that give us a sort of "high" that we really enjoy. Part of the hard wired animal in us always offering us a "hit" if we spread the proverbial seed.
Studies have also shown that when we more closely bond with a woman, over time, the brain tapers off the feel-good new relationship chemicals, and replaced them with a new steady stream of more subtle, but equally as strong chemicals that give us the feeling we've come to call "love", or "closeness".
We are, it would seem, nothing more than brain drug "addicts"
We find ourselves in long term loving relationships, but when we see a new attractive woman, it's like a crack addict seeing a rock. And when we're flying high on new relationship energy (NRE), we feel there's something missing if we do not have the "love" chemicals.Now of course it's not so simple as this, add human intellectual complexities to the mix and it becomes a real Lollapalooza.
This is why, IMHO, monogamy is counter to human nature. Why should it be that when you meet a woman, and fall in love, you should then forever forsake the thrill and joy of NRE?
That's one of the reasons my wife and I are polyamorous. But that's a whole new can of worms.
Best of luck in your quandary!
