Um, absolutely, to the last comment.
Your Father-In-Law to be is "opinionated" and as such he'll always love arguments to prove he is right.
He is also, a control freak - a leader - all must follow.
Possibly even when you marry, he'll say "excuse me family matter", as you haven't been in it long enough, or your not blood as to the reason if you asked why? I am?
Your Fiance probably never ever stood up for himself but hopefully he doesn't have similar traits? Or, else you'll get it from all ends... lol...
We can choose our friends/partners but not our parents...
Distance will also cause grief in the long run...
I'd jokingly start standing up for myself.
My Father is a bit opinionated ( alot ), but he is such a softy with lots of love to...
My Sister-in-law ( 25 years later ) and him get on real well, because she gave him what for after getting over the fear of him, lol, and still does but in a jokey way, not nasty ... That seems to go down with his ego, a bit like flirting.
If that makes sense..
So, not disagreeing with him on everything but oh come on, you know I'll be family soon, might as well let me in now, type of thing and laugh but walk of...
Good luck!!
