So now you know she's testing you, and now you know she has a jealous side when it comes to you which is impressive for someone who wants to leave you.
And yes I'm a smart a$$ and I wouldn't change it for the world. Life's too short not to have fun.
So you backslid a bit but you also did a few things correctly so all in all it's a good learning experience so far. More days like this will come, some will be easier, some will be harder, it's ok though, you can handle it.
