Background Check

My family, specifically my mother, went behind my back, did a background check on my BF, looked him up on public records before I could tell her what’s been happening.My mother told MY ENTIRE Family—aunts, uncles, grandparents who are SUPER SICK & DYING. Now, my entire family won’t even say hello to him. They are CONSTANTLY hounding me every time they see me to break up with him & are starting to set me aside now. They don’t let up AT ALL. My BF & I have shared all this & are actually at a very good place right now. His record is not the best & he knows I’m not proud of him in that aspect. I NEED some of your insights as to what to do with family & my relationship.
