Will I ever overcome my partner's (almost) cheating?

So, 1 year ago, my friend and I messaged my boyfriend from a fake account, sent him some photos and he took the bait, he sent one as well. I immediately confronted him and went nuts. I was sure I was gonna break up with him but I could not bring myself to do it, so we sorta tried to resolve things out.

Since then, I regularly think about this incidence and sometimes become mad at him out of nowhere. I love him, I know he will not do anything like this at least any time soon and things are pretty serious between us now (this was one of the reasons that I couldn't break up with him, our fanilies are involved and I'm from a middle east household).

So, I really want to get over it and move on, but I don't seem to be making a big progress now. Will it be possible, ever?
