It's not my intention by sending this to try and win my FIL over my side, actually.
I feel that I honestly need to apologize to FIL for the way I acted, and the emotional pain I inflicted on his daughter.
FIL's a good man, and I hurt his daughter. I respect him, and I think I feel that owning up is the right thing to do. The reason it's a letter is because he lives 2.5 hours away...and, I don't know how coherent I could be on the phone (Plus I've totally used up my non-Verizon minutes this month anyway, so I can't make phone calls :P ).
At least, what I wrote in this post is the intention.
