It is strange that he cuts you off after you USED to get on well.

Sounds like he has lost his way emotionally and needs to talk to a professional, someone he can unload to.

Maybe he's pushing you away because you know the real man, the one who was funny and cared for others. Seeing you, will remind him of how much he has changed and it doesn't sound like he wants to be reminded.

It also sounds like he has tied his self worth to money/career instead of family/friends. He needs to slow down before he kills himself with stress and learn to live life properly.

Saying all that, how dare he be so thoughless and hurtful to you, his once beloved sister.

IMO I would ring him up explain that he has changed and not for the better, tell him how much he hurt you and how much you miss the caring brother you used to have. But that you still love him and when he wants to grow up, you'll be here for him.

I would have your normal christmas with Hubby & Father and try not to worry about the brother, sounds like he has issues. Try and enjoy yourself with your loving husband and father.

{{{Hugs}}} to you.
