aftermath of relationship struggles

i’ve been with my bf for a year and a month now, and we’ve had our fair share of struggles. i feel like we’re finally at a good point in our relationship, a point that (at least from my side) i really like and was striving for. the thing is i keep thinking about how things went in the past and the way things were and it still hurts. i personally hope i stop feeling this way entirely and wish to look past it, but i just wonder if that can even happen? is this something that ill be able to look past eventually?
