So I just recently got engaged and have been on Cloud 9 with my FI and my family, however, it seems like his dad is not excited about the engagement/future marriage. The day after the proposal we went by his parent's house to speak and when we got out of the car his dad was outside and blatantly ignored us. His mom and grandmother are both excited but his dad went so far as to barely even speak to me when we left.
The next day his father met with us and started by saying "congratulations, but I wish I would have known about you proposing", which was a blatant lie (he told me that his father just said "good luck" when he talked about proposing-yeah kinda harsh). He also basically blamed us for his brother's (who has autism) depression. He also said that my FI was talking mean to his brother and doesn't spend much time with him(another blatant lie- 1) he LOVES his brother and even was planning for his brother to move in, which he declined; 2 He just got settled in his own house so he not around his brother most of the time). His father kept saying that it wasn't our fault but kept saying how us getting together caused the depression.
What hurts me most is that I was pretty close with my FI father and it seemed like everything changed as soon as he proposed. His father always disrespects, talks down and blames him for the negative things that happen, but now for some reason, he's seeming to attempt to do the same thing to me. I just wanted to know am I looking at this the wrong way and what do I need to do?
