Reaction to Talking in Bed

Talking in Bed to me, seemed like a paradox. Throughout the poem there were so many opposites - 'easiest' and 'unrest', 'honest' and 'untrue', 'together' and 'isolation'. I think that as you read the poem, it becomes apparent that this is not young love, but middle aged/old love, something that has lasted for a long time. I think there is a message towards the end of how young loves words are 'true and kind' but when love has aged, it no longer stays that way and I think that perhaps Larkin is saying here that being kind is not always being true.
