I love a very direct person, she might be teasing but that confidence is so good.
Just with the current context, I relate to the feeling of being anxious and someone close being anxious too, and it is quite hard to focus on yourself with that extra baggage. But if his anxiety was the problem (prolly not, ex prolly has some other reason like average misunderstanding romance stories) bro hasn't worked on it if he's still devastated by it. But then again not a lot of context, for now shes valid for me, they were young and theres still lots of life to experience, if she wanted to focus on herself then its fine, but bro has to move on.
