RTL, I completely understand where you are coming from. For our son's b-day I had a guy she was dating come to the party. This was before I even knew they were an item but it still hurt me. He even came to her Christmas Eve dinner as well. I am afraid to say that decency and our STBX's will not collide in the same sentences for quite some time.
As for the debt and assets, stand strong. I too felt as if I would just walk away and leave things but what is the point to that? You have to fight for yourself and think about your future as well. I too am having to fight for everything, even time with our S. It is not fair and it is even tougher to remain decent through all of this.
As for the depression, find a support group, talk to a counselor, confide in a friend, it will be something that will help you through this. My STBX hated the fact that I spoke about my problems to people she knew but it no longer was about her, it was about my problems. Also, get out and be around people. even if it is dinner by yourself or even a dinner date with your D. It is somewhat refreshing to just get out of the same old routine. It has helped me and even allowed me to make some connections with other people.
Do this on your terms, you are the only one that can change you. Do it for you though as well as your daughter and then it will be even more rewarding in the long run.
