OP's brother passed away and left a big trust fund for his son (OP's nephew). Until recently OP helped his sister-in-law out with handmade things like beds, wardrobes, and birthday gifts until the new husband called him cheap and because of this OP won't help her out anymore. Then the new husband said he would take money out of OP's nephew's trust fund to pay for his unborn children since OP doesn't want to help anymore.
