Overwhelmed and Insecure - I'm So Mad That I've Done That!

My husband and i invested in a property with my daughter and her husband. They considered themselves 50 % partners, not minority investors. We disagreed on this, but they refused to be wrong about it. When we spoke our truth and stood up for ourselves, they fought back hard. I used horrible sarcastic words, but only because we were right and we needed out. Our daughter accused us of all kinds of things,. My son in law was disrespectful, sarcastic, manipulative and used psychological warfare. Now things are settled, and we thought all was well. It's heartbreaking.They've spoken their truth and we've spoken ours. So he believes he's always right, and he will not bend.
