Hi Nikki!
Welcome to PsychCentral!!!
I know too well how you feel. I'm actually feeling depressed because
I'm going to be away next week. I considered planning my vacation around my therapy session (which I probably could have moved to Monday) but decided I really should take the whole week (and both weekends) off. But I always miss him when I'm away.
When he's away, I don't ask him much about what he did. Sometimes he will say something about his trip if he's somehow making an analogy. Today when I saw him he had just returned from a trip (though luckily it hadn't interfered with the days I see him). For the first time ever, I asked him how his trip was. I didn't ask him where he went or anything like that, but he mentioned that it was good. I noticed that his cold was gone (he'd been hoarse the week before), and I commented on that. He said he'd gotten lots of rest on his break. I was glad for him. I assume he travels with his family (or at least his wife) for vacation. But I don't mind not knowing the details. He gives me a few details about his life, but it's always in a therapy context (like if he's explaining something about relationships or something).
Anyway, it sucks when he's away so I feel for you.

Next week I'll be sad when
I'm away! I might have to call him, but I rarely do in-between times. He'd allow it, but I'm very nervous about being too demanding.
