Tad, No, she's not trying to get to you. Some crisis people do stuff like this. For example, my xh was gone 6 years and we were divorced 3 years and I get a call from his auto insurance company wanting to speak to him about his new vehicle and what insurance he wanted updated. When I asked how they got my number, the woman said he had given it to her. Did I sit there and think he was trying to get to me? No, I thought he was just plain nuts, but I did inform him after the holiday weekend to contact his insurance agent about he call and I also advised her that my number is to be removed from whatever paperwork he had given her.
Sometimes they do things and really don't think about it. Maybe your number was given off the top of her head at that time...but whatever the reason, you need to stop thinking that she's trying to get at you. She's married and moved on and you are still sitting there thinking each and every time she does something, she's doing it to get at you. This is not always the case. They are just plain out to lunch.
Tad, you need to start looking at your situation a bit differently and try to find some humor in some of the stuff she does. Sometimes they do things for attention and the only way to get it is to pull the rabbits out of the hat, i.e., whether it's positive or negative and again sometimes it's done w/o thinking about the consequences of their actions. Bottom line, you have to let this stuff go.
Keep your focus on your upcoming interview. That is what is important right now. Leave your xh to her new husband. She's his problem now, not yours.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
