Do You Believe That "Once A Cheater-Always A Cheater"?

Some people say it's true, that once a cheater, always a cheater but I don't know if I believe that entirely. I honestly think that some people are cheaters and that's what they want to do, but I think that there are some people out there who really don't cheat because they want to, but because they made a bad decision and are very remorseful for what they did to their family. I am not sure what the statistics are on that, but I would really like to know. As for my situation, it happened more than once, and with more than one woman, and he was NOT remorseful and didn't want to try and make amends of things. Sad but true. And do you stay with someone who is a repeat cheater? I tried but it didn't work out for me......he was just too into the other woman and it was too much for me to try and change. However, if you are with someone who has only cheated one time and is remorseful and wants to make things work out with your marriage/relationship, there may be hope for you after all. It is honestly hard to get the cheating out of your mind, but you can forgive, it that's what you are willing to do. Getting through infidelity really does take time.....this is just not something that you can work through quickly at all, because if you are willing to work it out, it takes time to get the trust back. Do you believe that saying "once a cheater, always a cheater"?
