Yep, she's rebounding and trying anything to make herself happy. You know as the rest of us that for most people, that's not a good life and will almost certainly come crashing down on her.
In a sense, she herself is trying to "GAL", although she doesn't know it.
You need to be doing the same thing, but not to THAT extreme. Go out more, rarely turn down an invite to do something, especially if it's something you've never done before.
Rediscover who "Jon" is and what he likes to do. Be good to yourself and treat yourself to an indulgence that you would not normally spend the time or money on.
