This is great news. The more I think about DB tactics the more I realize that it is not one size fits all. Does the phrase "do what works" ring a bell? I would approach this with caution. There is a big difference between over pursuing and showing you are still interested.
I think you have handled the situation very well; you however have a very big advantage over most. The FIL is in your corner and he knows best. I am not saying go crazy but maybe test the waters a little bit. Something small.
If there is interest then follow through if she goes cold then back away. You guys have a great chance here you run into your W on occasion use every meeting as a chance to succeed. I say wait for the meet with FIL and then make a smart decision. DB does not mean go dark and when W shows interest keep going dark.
