My bf's mother is a ************* not nice lady.

I am so frustrated that I could scream. I mean deep down scream, you know when your 2 y/o just stands in the middle of the floor and screams, well that's me right now. Not that this thing that has made me so mad is a big deal but it's just snowballing right now. She works at a bank and even though it's not right to do she has been telling us all summer she would get money for us when we go to the nascar race in New Hampshire. She can get a better exchange than we do at the bank normally. I went today to get the money, 500 US funds cost me 570.01 Can. She could have saved us 35 Can. Not that that will break the bank but it's a little extra she could have saved us but no no no, now she can't b/c she's nervous she'll get caught. I bet if bf's ex wife wanted some she would get it. OOOHHHHHHH I do not like her!!!!!!And my bf doesn't say anything cause she exchanged money for him so that's all he cares about. I know it's his mother but for the love of %&*(, why can't he agree with me that that wasn't a nice thing for her to do. It just adds on to all the other crap she does. I need a vacation and when we get back if he doesn't start supporting me when it comes to his mother, I'm leaving so fast the dust I leave behind will choke him. God I'm livid right now and it's not even that TOM. Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
