I am happily married, almost 10 years, don't understand why some people have to cheat?

If you really think it feels better to be with someone else, then just break up/divorce first, then you can be with someone else with no issue, right?

Why secretly cheat, sometimes for many years too? What is the logic?

Want to experience different feel with many partners at the same time? Don't be in a relationship then, just be a "player" with other consensual "players", nobody gets hurt and you can enjoy as many different partners as you want.

Or if want to be in "open" relationship, get your partner's consent first, then can date whoever you want, don't cheat after your partner rejected your "open" preference, just break up or divorce first, find someone else that shares your open idea, easy right?

I really don't understand the psychology of cheaters, makes no sense.

After exposed, they beg for forgiveness, cry like children.  :stars:

Cheaters with kids even worse, why hurt your whole family like that? Just divorce first, say you no longer feel the same way, then date whoever you want, as long as you take care of your kids afterward.

Sometimes both have kids, still cheat with each other, ruin two families at same time, wtf?  :stars:

I cannot understand these people, no logic at all.

Maybe it's like drug addiction, cannot stop once started, brain and body out of control?  :stars:

What sort of character and money from who?

Men or women? Men totally not to blame?
How can you not know you are cheating? Having feeling is one thing, but to actively pursue it and "pairing" with another, behind your partner's back, is not exactly an "accident".

How to justify?
How to justify though? You still need to actively engage in the cheating, it's not an accident, chance or not.
