You're right. Whatever she does now is not about you. And whatever you do from now on should not be about her...at all! Who cares if it's a shot at you? I doubt that it is though! Who cares if it's so that other people know she's single? These are things that we have no control over...so why bother? Does it make sense to let stuff like this occupy real estate in our brains? Nope!
How are you doing?
