<human>: I can't believe I've come to asking for advice from complete strangers, but I feel so trapped.

He's very disrespectful, constantly challenging me in the most passive aggressive ways and finds every opportunity to flaunt his money.  (He is a very successful businessman, and although I'm by no means poor, I'm certainly not making millions of dollars.)  On top of that, even though my fiancee agrees with me that his behavior is totally inappropriate, she keeps asking me to trust and have faith in him that eventually he'll show his true and loving side.  I completely disagree... I think this is going to be a tough ride for me and I just need some perspective or advice or something... I don't know... I feel just so lost.  

Thanks in advance.

Can you condense the text into three sentences or less?
<bot>: Father in law and I don't get along.  Really putting a strain on my relationship with my fiancee.  Please give me some perspective.
