Once a cheater always a cheater?

If you truly love each other I believe you can work it out. I think everyone deserves a second chance. Perhaps it was just that she was too immature at that time. Of course this depends on the situation. If she had cheated on you multiple times, and continue to do that, that might be a different story. Just take it slow and easy. You will both have to learn to trust each other and start fresh and new if you're going to do this. Are you both still married to each other? If you are, put all things behind you and start fresh and make the rule there's no bringing up the past on either side. However if you are not married, I would not remarry her until you both can trust each other. But then again maybe you don't want to remarry at all if you're single. Given that she has come back to you and asked to try again I assume, then perhaps she has grown up now and sees what she had and misses that. Maybe now she's ready and more mature. Time will tell. I wish you the best.

Start with the understanding that if she cheats, she gets kicked to the curb. No mercy, no warning. I have been married for 32 years, my wife and I had a "come to Jesus" meeting today, I have a new bank account, my direct deposit has been changed, her responsibility is half of the household expenses and if she can't get her head straight, I will file for divorce.

Take it from someone who knows if you're not willing to accept her cheating than it's best to let her go, even if you work it out the trust is gone and you'll always think about it, and when things aren't going right you'll always use the fact that she cheated.

Cheetahs can now identify as any animal they wish. This has been raised as a concern in Antelope only bathrooms.

Some people cheat out of habit. That is harder to change.
Some people cheat out of circumstance. That is easier to change because it is not really in their nature.

As long as the cheater remains far away from you and with no further communication (besides kids related if there are), it´s totally feasable to work it out in terms of keeping it civil.
The cheater may of course become a better human being.
But you don´t need to be the Guinea Pig of the experience,

People make mistakes. Strong people can work out almost anything if there is a genuine sincere effort to make it right. But not everyone is that secure in their lives. Some people experience the wrong and can't find the strength to get past the mistakes. Too bad for them.

I have always insisted on non-monogamous relationships.
There's no way I could eat the same thing for dinner, every night, for the rest of my life.

Habits are hard to change without deep realisation. And deep realisations are hard to come by. So yeah, once a cheater always a cheater.

You havee to establish trust or forever be worried. If it really effects you you have to talk to her. Communication is a big deal with anyone you talk to. If she actually loves you she won't do it.

She will cheat again because you allow her back in your life which is letting her get away with any previous cheating.Who says she cheated just once?Her?

*THERE is real love...

I don’t think cheating always means betrayal. Maybe the partner refuses to have sex, or neglects emotionally.
