We all fall prey to temptation in body and spirit and if you have cheated on him then you will have to do a lot to win back his trust.
You have hurt not only your relationship but also caused his ego a great deal of damage and winning him back is going to take some time and perseverance on your part.
Here is how you can attempt to win him back.
Be prepared to see results after a considerable period of time Things are not going to happen overnight and you will have to keep trying.
Initially all your efforts to patch up will be stonewalled by him as he will be hurting real bad and he will want to exact revenge on you.
Don't give up hope if you meet some stiff resistance.
Do your time There is an old saying "what goes around comes around".
So, if your guy decides to ignore you or if he decides to not talk to you, you will have to respect his feelings and stay away from him.
He will need lot of time to come to terms and you have to be patient.
Just convince yourself that you are doing time for the crime you committed.
Let him figure out the reason for your actions When you leave him alone he will cool down after a while and will begin to analyze your actions more rationally.
And if you are lucky he will see why you did what you did.
While he is figuring this out, you stay clear.
Look back and come to some sort of conclusion While your man is dealing with his grief, try and understand the reason why you committed infidelity.
You have to think and crystallize the reasons for your act.
This will enable you to address the reasons and come to some sort of conclusion.
If needed you should seek professional help to understand your actions.
Maintain a low profile To punish you your man might resort to dating other women.
If he does that then maintain a low profile.
Don't assume that he has moved on.
Instead maintain a distance and let him have his small revenge.
Don't start socializing with other men or male colleagues as that will send a wrong message.
Say the magic word Once you are convinced that he has cooled down sufficiently seek an appointment to meet him.
The first thing you should do as and when you meet him is apologize sincerely.
Saying sorry with a capital 'S' will calm him down.
Tell your man that you regret your actions and tell him that it will not happen again.
After that you may have a small conversation and make a graceful exit.
Make amends From now on be your usual self.
However, do meet him and keep in touch.
He will watch you closely and only when he is convinced that you have reformed yourself will he begin to warm up to you once again.
