This doesn't really have anything to do with the wedding, just my FMIL. My fiance's stepmom is psycho! We are in the process of trying to find a house which they have offered to help us pay the down payment on (they are forking over a lot for the wedding as well). I can't say anything to even remotely upset her, because she'll twist it around and go off the deep end.
For example, she found a realtor's number about a house, I told her that I would just drive by the house, see if it was worth looking in to before I called the realtor. She snapped and assumed I was disrespectful and unappreciative (I wasn't) and has threatened not only to not help us pay for a house, but also to not help us pay for the wedding. I'm not a door mat, and I usually speak my mind to anybody, but if even the slightest thing is making her threaten cutting us off, I don't know how I'm going to stand her! My fiance keeps telling me to turn the other cheek, but if she keeps doing stuff like this for the rest of our lives, I'm not sure I'll be able to.
Anyone have advice on how to deal with her whenever she goes psycho on us again?
