Remember what Michele says in DR, have no expectations about these invitations!! It is perfectly fine to invite the WAS along to an activity that you are already planning, but if she doesn't go, then no big deal, because you ARE GOING ANYWAY. You have got to get to the point where you truly don't care whether she goes or not. You invite her, if she says no then you shrug your shoulders and go and enjoy yourself anyway. That doesn't mean you have to invite her to every single thing you do, but it's OK to invite her now and then. Also, she may legitimately have had a headache. If she really did, do you think it was fair to her for you to be PO'd about her not going? Would you even want her to go if she had a splitting headache?
That is just it. I wasn't PO'd. I have invited her on several occasions, and she has chosen not to attend most of them. I am not mad. I wasn't short with her. I did shrug it off and we did carry on with our plans. I was simply expressing that I would rather not invite someone who always, or at least usually, declines my invitations. I would assume the same attitude towards a casual friend. It is very common interaction among people, at least I feel that to be the case.
