I went back and thought about my time line, and I first realized something was wrong in the Spring of 2014. I didn't get the official BD until almost a year later, so March 2015. So I'm now almost 3.5 years post-BD, and a full 4.5 years since I knew there was something bad happening. You're pretty much on a similar trajectory, most likely. You'll get there.
It might be out of place to say it on this site (devoted, as it is, to reconciliation), but don't underestimate sex and its healing powers. I am not talking about jumping right into a relationship with the first willing partner, but I'd be lying if I said getting it on with somebody knew who was really into it didn't jump start the healing.
