The INLY way to fix it is for yiu ti change. If yiu TRULY have the desire to change & are willing ti to the hard work it takes in therapy for yourself first. Then if successful & your marriage is still in existance & you have PROVED you have changed to your wife then couples counselling is the next step to wirk on fixung the damage you have done to the marriage & work on rebuilding trust.

If yiu have no desire to really change don't waste any more of your wifes time & life. Let her go if you aren't willing to do the work it takea to change.

EVERYONE is capable of change but it only happens if the desire is great enough. Hope you are willing to do this for your wife & marriage.
