my MIL is a nutter part 2

So I can hear her yelled at someone through the wall right now. Apparently she also threatened to cut my husband out of her will, like she's his mother, why would he care about getting money or not? She's stopped talking to me, not sure whether I should but upset or super happy...okay, I'm actually elated right now that I'm not on the receiving end of what's going on next door, I just hope it's not my husband.
