1.) If anyone gets engaged she asks prices, and then says any rings that don't come from Zales are basically cheap pieces of glass with spray painted copper.

2.) She got pregnant after my miscarriage because "let down the family."

3.) Now that she has a baby, she constantly asks if I'm pregnant. She cannot go a minute into a conversation without asking if I'm knocked up yet.

4.) When my SO and I offered to take her, SOs brother, and their parents out for a dance dinner, she called MIL crying saying how she "knew we'd be announcing our pregnancy and that how she felt hurt and mad that we were having a baby and I didn't deserve one because we weren't married" (not important to me, no plans to be married till I get the position I want in my job, 10+years).

His whole family let's SIL get away with it because she's a pretty little blond and not very smart.
