I don't think there's anything mature/immature about feeling what you feel? I also think some things will "resolve" when you see him again and, if nothing else, you can "sulk" if you want :-) that he's been away and he'll see it. I always kind of "liked" going to the session after my T had been away because of the conflict with wanting to sulk and yet now she was back and I was "safe" and things were "normal" again. The tension pulling me each way was kind of interesting for me to feel and try to deal with; the horrible time is over versus it shouldn't have happened in the first place, I hate you :-)
