OP,

In your follow-up posts, you keep defending yourself and blaming your current boyfriend. You need to stop blaming him and admit that what you've done is indefensible. Every guy looks at porn, that's just a fact. He probably tried to deny it because he knew you were insecure and would overreact, which is exactly what happened. You internalized a common male preoccupation into a complete critique of your looks. Then you crossed the line by cheating on him.

My advice? You are way too insecure, petty and immature to be in a relationship. Tell him what happened and break up with him and get out of his life immediately. Then, work on your issues ALONE.

It doesn't seem like he is doing anything wrong here, like someone said earilier, all men look at porn. The pics of ex are bad, but is there any physical contact like with her, like you have had with your ex now?

I agree with huntersbar,which is to start fresh! take time out to figure out what you really did to yourself and your boyfriend by cheating
