Future in-laws

Y’all. My future in-laws aren’t my ideal in-laws. My mother in law is sweet and kind, but she’s super boring. I like her, though. She just doesn’t get jokes or have a sense of humor and I’m bubbly and outgoing. But, my future father in law is the real problem.

I am a super positive person as are my parents. We are always smiling and laughing and joking and “not sweating the small stuff”. We rarely complain and even when things are bad, we look for the good or have hope.

I’ve been working through the past two years of trying to not let my future father in law bring me down, but he is sooooo negative. It’s like nothing I’ve ever seen before. He complains about EVERYTHING. I invited my future mother in law wedding dress shopping with me bc she has 2 sons, and her oldest eloped. I just thought it would be nice for her to be there. His dad invited himself (bc he didn’t want to drive in to the “city” to hang with my fiancé/his son while the ladies dress shopped). The entire time he was so negative. Rolled his eyes and made fun of my friends and mom for getting emotional. This was a huge deal for me and I tried so hard to not let him ruin it, but his attitude put a cloud on the day. It’s always like this and I just don’t know what to do.

It’s gotten to the point where I am thinking of staying home with my parents for longer during the holidays to avoid his parents visiting us.

Help! I just need advice. His negativity is draining and as an empath, I feel other emotions intensely, so when he is being negative, it rubs off on me a lot.
