I'm happily married with three daughters. I stay happily married because I do my share, expect my wife to do hers, and decline to be a doormat for anyone. Among my circle of friends, I do not have anybody who dumped his wife in order to get a "newer model", but have several whose wives dumped them in order to move on to a bigger, better, deal
I've looked at your comments on other threads. The only threads you seems to have any interest in participating in are the ones where you can vent your anger and unhappiness at men, and complain about how badly you were treated by your ex-husband in your own failed marriage (eg, your posts #137, #258, and #259 in Young men are running from marriage )
Come up to the present. I am not your ex-husband. Nobody else here is your ex-husband either. It's time to resume your life and move on. I realize (as you mention in #259 above) that good men may be hard to find -- but you will never find one as long as you have that enormous chip on your shoulder -- the one that whacks any nearby guy across the face every time you turn around
