Help! Internet Chat Problem

I am new to this forum so please forgive me if I am posting in the wrong place.
I am hoping people here could help me with a problem I am having.
I have been married for over five years now and have gone through some real difficult times in the initial part of my marriage. I could not get a decent job, was living with my parents, and the final blow came when I found out that we could not have children about two years after our marriage. I hit an all time low.

For some reason I started looking for comfort elsewhere. My wife and I were not on the best of terms at this stage and would argue and fight over stupid things. All sorts of thoughts would go throught my mind. I felt very lonely and began chatting to strange women on the internet. Most of them did not maintain any long term contact besides one. A divorced, muslim revert. I spoke to her for a period of about 4 - 6 months and found myself becoming emotionally involved with her. We never met each other in this time, but I did call her twice just to speak to her. She sent me photo's of herself, but I never did in return. She did not even know my real name or what I looked like. After realising this attachment to her I began to feel guilty and made a resolution that I would never contact her, and made a stupid mistake of telling my wife about it, though I never told her that I was emotionally involved.

Like all women, she obviously felt I cheated on her etc. and till now she still does not trust me and constantly reminds me of what I did, and this saddens me even further, but I pray allah grant her nothing but Jannatul Firdous for her patience and the difficulty that I put her through. Though I know what I did was wrong and never justify any of it, I still have this very strong urge to contact her every now and then. I have succumed to this several times and am having an incredibly difficult time of letting go completely. Any advice would be appreciated.

Jazakallah
