Should I tell my gf?

This is from someone who has been into porn for a very long time, addicted since my teenage years (I am almost 30 now) and who has recently finally opened up and admitted to the extent of my porn addiction (as well as affairs).

There is no "well" way any woman could take this. I know that some women would be more understanding if they are experience with addiction. But in my brief experience, you need to tell her. Hiding it will continue to weigh on you. She will continue to notice it. Your depression will slip further and further. She'll become worn out, frustrated because she can't help you through it. She'll begin to blame herself.

Take all that and more versus telling her. She will be shocked, and confused, and hurt... but she'll know. And you'll have this secret off of your chest that's like an infection. It worms its way into your heart and feeds on your to survive. It puts up walls to protect itself, winding and twisting its way deeper and deeper, making it all the more difficult to get out. Once it's out, completely, there is a very real clarity that comes with that. You stop juggling the secret in your mind. You stop obsessing over the problem and are free to search for a solution. And your wife, seeing your honesty, unprompted, will appreciate that. She'll see your courage. I wish to God I had had the courage to own up to all my behavior and lies a long time ago. My marriage would have been for sure saved in that moment. Instead, I have completely lost her trust. Not because of the behaviors. Because of the secrecy and lies. They are more destructive than porn addiction, that I can say for a fact.

Pray to God to grant you courage and strength. Let him guide you. You will be thanking him afterwards.
"God, grant me the serenity to accept the things I cannot change, the courage to change the things that I can, and the wisdom to know the difference." This is a very powerful prayer, especially if you pay attention to the words. Please, go with God and have the courage to tell your wife the whole truth

 

The Middle East part is tricky. We are here as well, and not sure it matters which country you are in, as the Sharia law I think is applied in all of them. If I were a bitch wife, I could have landed my husband in prison or at least get him a hefty fine - all it would take would be for me to call the police on the DDay and show them his computer. It has been done before, where people landed their spouses in jail for having an affair. And it is impossible to predict how your girlfriend would handle the truth, as the emotions at the moment of finding out are not something she will have much control over.
Are you seeing a therapist for your depression? If yes, maybe it would be an idea to have a session together and maybe the therapist could facilitate the disclosure in a way which would make it easier to process? If not, I would strongly suggest you find one. There are wonderful therapists here with a lot of experience in dealing with PA, as it is not an uncommon issue, even in this part of the world.
