I love DW, but I have my own friends and activities that I like to do with others, and she does too. For example she meets her buddies for walk/run and coffee every Sat morning - I'd rather a sharp stick in the eye than to sit through that with them, but she loves it and that's all that matters. Besides she usually brings me home an almond croissant, what's not to like?
We don't like to be apart overnight, but during the day some days by all means. I think it's best if both of us have our own lives & identities apart from each other as well as together. YMMV
