Why does my brother let me down and my sister-in-law revel in it?

hiya, she is making it very clear,that she does not want to be around you and your dad and your family.she does not sound a nice person at all.your brother is no better for him to know what she is doing,yet agree with her.i would not put yourself out again,at any time.and i would not invite them to any think in the Future.go away next year,and don't give them a second look .if your brother is upset on what you are doing,then let him come to your house,and let him tell you to your face.i don't think he will say any think.but he does not care about any ones family,only his own wife and kids.x
