Being Alone Sucks

I am a family man and here I sit at home alone taking down the Christmas decorations. My now separated wife of 40 years came over to the house we built together to have a Christmas party with our family of 5 kids and 5 grandkids and now the holidays are over. I really hate being alone at this time. Having a really hard day undecorating the tree that is always covered with the decorations my wife and I bought from places we would go on vacation. She didn’t want to take any of the decorations with her when she moved out. I wish I could understand why she doesn’t love me anymore. I am not a bad person.
