I imagine you always will. I have fondness for my XW as well. I'm past wanting to be married to her or have any kind of romantic relationship with her, but I will always love her as a person and someone that was special to me for a long time. Your kids are very young, so you and your W will have a co-parenting relationship for quite some time, and really will probably interact on some level for the rest of your lives. So resolving things peacefully is definitely paving the way to a better future no matter what type of R you end up having with her.
