Honestly.. I would much rather you do this face to face.
If things are changing... hold off.
If things stay the same way.. write the "Card" to the FIL.
Now when you write it.. write it like he was your dad. Put yourself in that mode. Don't be too scared of the emotion in it.
Adult Daughter.. to her Dad.
This does 2 things. It ties to some of his emotion.. even if he does not have a D. Then it comes from a man's perspective to everyone else. Now.. my thought is.. men don't like "Drama". Also they like when women talk to them. So.. the "Drama" may be controlled a bit.. and he will appreciate it. Now this has the side effect of the MIL will see thru it. Which in turn.. will take the focus off you. In my mind.. it puts alot of filters on it. It leaves you with trying to "fix" you and MIL. Maybe.
I don't envy you at all.
Relax Eat Think Act normal React.. Smartly. Do something different. Emulate. Do Work.
