I got affair with last one year before some girl. But that not for sexual affair. My wife known that affair. Now she never trust me. But I need to become good man. Please help me.

Time is the only way to regain trust.
There are other things to do, but all of them need time to prove that actions are what count, not promises.

Write her a letter. Spend a lot of thought on it. Tell her why you love her and wanted to marry her, and cannot imagine your life without her. Make no excuses. Having a letter is something she can read over and over, when spoken words are forgotten.
Tell her that much as you want to make promises, you don't expect her to believe them now, and that you will show her in what you do that in time she can trust you again.

Spend as much time as you possibly can with her. Walk hand in hand on a nice day, and buy her some flowers. But don't start 'buying' her love with expensive gifts. Any gift you give her must be given with lots of attention first.

Thanks for the advise. But she's my wife. I'm working at overseas. Every time she told to me need to divorce. I know my fault that. I will go my home next April. What can do now

I know she's your wife. Read my answer carefully. You need to woo her all over again.

OK I got your point. What your idea I will go for the vacation. But she not happy to see to me. I everyday called and sms her. But never reply. Why she doing that. Really appreciate your kind cooperation.

You appear to be looking at this from only your point of view and how you feel. Think about it from hers.

She is hurt and angry. You betrayed her trust.

If it wasn't a physical affair it was an emotional one. That means you shared an emotional bond with a woman who was not her. If she had a bond with another man, how upset would you be?

You have to give her time to let the hurt go and heal. IF she is willing to let it go. It doesn't sound as if she is. She has told you she wants a divorce. At very best, she needs time and space. Back off and give her the time to calm down. Daily trying to talk to her is keeping the wound open.

At this time there is no wooing. Your attempts at wooing may be calling into question why you didn't do this before and if you did this for the other woman.

All you can do is develop interests that can occupy your down time and keep you from crossing the boundary again. Work on improving yourself and showing her that you are being faithful not only in body but emotionally.

Hopefully, she will calm down enough to give you the chance to regain her trust. Understand that it won't be easy and will probably take longer because you are apart. You might see if you can find on-line marriage counseling and ask if she would be willing to give it a try.

When you say 'next April' do you mean 2011 or 2012?

Thanks for the advice, I will go this April 8th on 2011.

I want to remove this question how can do this

You can't. What happened, if you don't mind saying? Did she take you back?

No never
