Hi roberto516,
That's good that you didn't grab her reply, but the second message that you sent telegraphs that it bothers you and that there's a bit of an attachment there because you if you weren't you wouldn't of sent the second one.
There's no right or wrong here and I understand that this work ( changing how we respond ) takes time and practice. I've been there. I used to have email threads where I'd be fighting with the ex by email for almost my entire shift, it was back and forth, it was both us trying blaming each other, I'd try to get her to change, I had knots in my stomach when I left work and I dreaded walking through the door because nothing was ever resolved.
Nobreply. I then send one more message asking if she can please respond so that I can plan when I'm going there.
I wouldn't send her another message, I'd prep myself for the open house tomorrow, you may or may not see her there, try to focus on you. Also you know her better than anyone on this board and if that's her sense her humor, that's her sense of humor. I wouldn't look into it too much, it'll drive you crazy.
