A 180 for me would be just simply saying have fun and ending the conversation at that point. I know everything she does is to get a reaction from me.
You don't know that for certain, your speculating and mind reading. You keep trying to analyze her actions and trying to understand her thinking, as we all do at times. She might be testing you to see if your still acting controlling, and doing the 180 as you mentioned above would be a good plan. She could also just be going to the beach as she is a different person now and it has nothing to do with you.
The issue is when you constantly think EVERYTHING shes doing is because of you, you think all shes doing is thinking of you. Shes not, you might not enter her mind much during the day.
In a previous post you mentioned how you said/wanted her to just tell you what she was doing instead of sneaking around. I believe you told her you just wanted her to be honest with you. You have expectations still of her to act like a W by telling you the truth about something. Shes not going to act like your W, so she really has no reason in her mind to tell you anything about what shes doing. If she wants to hide it from you it could also be for many reasons.
Accept what is, let go of what was, and have faith in what will be
