I remember many moons ago some tale about giving oneself about half the time of the relationship to have moved on. I do understand and can relate to how years later having some memories or old wounds come to light. In all actuality I had an internal memory moment today where I had received a compliment from a family member about some quality of mine and I literally flashed back to something my distant exbf had insulted me(my educator/educational university) about under the same umbrella/category. So something from 8 years ago doesn't seem too unusual.
