My t said to look at their other relationships. Are they kind, forgiving, rude, judgemental.

I've always heard to look at how they treat their mother. Kinda like what you said, if he treats her like a slave he'll treat you like one.

I've also heard to look at how they treat waitresses/waiters. If they're rude or ungrateful, that can tell you a lot about a person.

My t is going to give me some sheets on Red Flags next Monday. I'll try to remember to put some of that information on here.
