3, it's a tough call to know what things to put in place when they are so all over the place.
My suggestion, is to flirt if YOU FEEL like flirting. Remove any expectations from the flirting and just do it because you feel like it, not that he wants it. If you do it now, he may feel like it is a ploy and not real, so keep that in mind.
This is one of those things you can try experimenting with and if it doesn't go well, then stop.
I know others might tell you it's too early to do these types of things, but I think you have to fit it to your situation. You will know when it is right. And only do it because you want too.
