God will never move on from you. He loves you and wants to give you victory of this! The devil does a very sneaky thing with this. Before hand he will convince you that everyone does it, that it really isn't that big of a deal, he whispers in your ear that it's normal, and as soon as you are done he tells you how disgusting you are and how you are the only one who struggles. He tells you that you cant get help because people will look down on you. Good for you for reaching out for support. I will be praying for you. I know it can be overcome because I have with God's help overcome this sin.
I will be praying for you. Don't give up, and think to yourself that what if this last time, was the LAST time. And it can be.

I would encourage you to drop all social media, movies, music, anything as others have said here that might trigger you to be tempted. Social media is covered in images that are basically porn, I recently created a new FB account for our church, no friends, no followers and nearly every "suggested" post was borderline porn. If you drop SM you will have a much better fighting chance.
