Back story.. FMIL has been causing problems purposely ever since we've started planning the wedding. She used to be THE perfect MIL before we moved in together, but now things have changed. FI is her "golden" child because he is the youngest, and she has said some pretty controlling things to me about our relationship/wedding, etc.
When FI and I set our date, FMIL took it upon herself to tell FI's cousin that he is our best man..without FI having a clue who he would even ask to be his best man. At this time, he barely even had all of his GM picked out.
So when we saw FI's cousin, he said HEY! I'm so excited to be your best man! We felt like complete idiots not knowing what he was talking about, and cousin admitted that FMIL is the one that told him. Regardless, he's still our best man because we couldn't just tell him no after it was decided for us (lol)
With only less than 2 months from the wedding, FI's cousin was talking to FMIL about him being the best man, toasts, etc. and FMIL INSISTED that he was not part of the wedding. So of course he was so extremely confused, so when he called FI and told him, we were shocked.
Even though everything is squared away now and we're on the same page, I'm still in such a daze about FMIL. What a lovely woman.
