I don't think that saying "I miss DH when he's away" is the answer. You either enjoy alone time or you don't. Missing your OH has nothing to do with it. .
If using this as the 'criteria', then yes, I love alone time. I love it when I finally get some time to myself. But, to be honest, I often struggle to know what to do with myself as I'm not used to it these days, and will become even more 'not used to it' once DD2 arrives I'm sure.
