Forgive and forget?

I caught my wife of 4 years cheating, so I broke it off. About three months later she told me she just made a mistake and wanted to get back together. I gave it a large amount of thought and decided not to, my dad always said "Once a cheater always a cheater." To my delightful surprise I met someone else about 6 months after that and we have been together and happy for 5 years. I know how hard it can be when you love someone and want to forgive them. The cold honest truth is if they cheated on you they never respected you to begin with and no amount of forgiveness will help that. They never will respect you. My advise would be to move on and find someone who loves and respects you. Whatever you do, in the end the best thing you can do for yourself is to forgive her and put her behind you and don't let it cause trust issues. I have seen friends never forgive someone for cheating. Then they ruin the rest of there relationships because they are afraid of the pain. Please I beg you move on and love again. Let yourself trust be venerable and take the risk of being hurt in the end what is life without a little risk.

She's trash. I don't care if you love her. She doesn't truly love you if she could do anything with another person. Cut her loose

It is completely normal to want her back, but don't do it.
Even if she really has changed her ways(which is highly unlikely) you will always be questioning it in the back of your mind, and it will be bad for both of you

I would leave her. She cheated on you once and she will cheat on you again.

All of these comments say don't let her back in and I feel I need to argue the opposite. Humans are impulsive and often make mistakes, not to mention cheat. Just because you've been cheated on doesn't mean she "doesn't respect you", since when is holding your sexual organs tight the end all be all of respect? Second chances exist for a reason, and a strict "once a cheater always a cheater" policy doesn't leave room for consideration to the situation which is always important. You feel like forgiving her, she feels like she loves you, maybe she was going through a difficult time and has learned. I think the /most/ vulnerable thing you could do is admit the pain that her cheating causes you and nonetheless forgive her and allow a second chance.

Yes it is normal to want to let her back, but don't do it. She will just do it to you again. In fact, it will be easier for her the next time because she knows that you are a big sucker and will just take her back again and again. I bet, if you really checked into it, she most likely got dumped by her last boyfriend for cheating on him too. She isn't going to change so why set yourself up for more hurt. If you want tell her you just want to be friends with benefits and screw her brains out while you find a real girlfriend.

Drop that bitch like the big, steaming deuce she is! Once a cheater, always a cheater; she's your ex for a reason!
