After nearly 3 1/2 years together I find it sweet that DH will still go to the bathroom to fart. He also indulges me in letting me talk drivel to him e.g the fantasy lives I've made up for my dogs.
My ex-H was a compete arse who showed me no respect whatsoever so these little things mean a lot to me.
What kind of things does your DP/DH do that makes him stand out from previous partners?
