Today was my son's birthday party, the 1st since his mother asked me for a separation, since I moved out about a month ago, and since her boyfriend moved in. I knew it was going to be rough as it was held at her parents with her family, my backup couldn't make it.

As expected, my son's anxiety got the better of him early on and he was a crying mess with my STBXW and I trying to calm him down. Nothing seemed to work until he asked for her boyfriend. That was the gut punch. I had to sit there while he calmed down with her BF and I realized that was it, she had finally taken the last thing I had. Since asking for the end back in January, she took my money, my home, my family, my dog, and now I can't even be a source of comfort for my kid. I have nothing left, I am just a guest in my son's life now. How do I go on? How do I live like this?
