I can’t stand my brother in-law’s gf(neither can anyone else in the family).I have to see her quite often as my husband’s family gets together frequently for birthdays and such(1-2 times a month)She’s pretty stuck up and cares about money alot(I find this funny as she didn’t grow up in a rich family and her and my brother in-law are terrible at managing theirs).They constantly try and show off new gadgets and other things when we see them, while blowing off bills and other money they owe his dad.I know she doesn’t like me,not that I care,so I was wondering what I could do while they’re around to get on her nerves without being obvious and flat out rude.In fact she doesn’t like me so much that they stopped coming to family functions when we announced we were getting married and didn’t start coming again(4 months later)til after our wedding, which they didn’t attend(we were married in Vegas but his father offered to pay for them to go),they also didn’t come to our reception a month later
