A communication must! Wbf and I went over different scenarios last night. Like, what to do if a person I am uncomfortable with was at an event, or saw her at the grocery store. This lead to talking about the AP and what to do if he or we ever run into her. I feel like we accomplished a lot talking about it all and my anxiety has tremendously lowered. My Wbf was great, as he reiterated how he wants to make me feel safe again. I think the conversation helped both of us, as he has a lot of anxiety over the chances of running into her as well and we now feel better prepared (even though it will still be very stressful).
We discussed how if you ever see her, to quietly say to the other that she has been spotted, to hold onto each other's hand tightly and make a quick exit. It is important for us to stick to each other if it ever happens. We discussed what to do if a friend of ours or a stranger hits on either one of us, among many other scenarios.
So a word of advice, taken from SisterMilkshake, go over scenarios! I feel much better prepared in the case of an emergency, such as coming around the corner to find AP standing there. When you discuss what to do, the chances of you freaking or doing the wrong thing are much less. So prepare! To me, it is a large part of better understanding boundaries... understanding what to do when/if they get crossed.
