ITH ~ That was GREAT advice from Daisy!! I totally agree and was about to tell you that I don't think that it is a good idea to write another email either, until I saw Daisy's post and she took the words out of my mouth .
I do believe that when you sent him the list of dates that he is aware that you are coming back on Thursday. You do not need to keep reminding him. It looks too controlling that you would almost be treating him like a child by reminding him again. He is a big boy you already told him.
Another thing that Daisy mention that is so on point is that yes you do seem to worry too much about how he is feeling and how this will affect him...how about you?? DBing is about taking care of yourself too sweetie!! At this point in time you need to realize that his feelings and how he is acting has nothing to do with you!!! You have been doing so good lately with your PMA and GAL please keep that up!!
Good luck with the new roommate at least that is only for a few more days..YIKES!!!
