Had a dream me and my ex (father of both my children) got married.

Well we were together almost six years, have one little girl and another on the way, but at the beginning of my pregnancy I found out he was using drugs so I left. And now I've been having dreams about us getting married and him being clean and being a part of our lives and its really getting me down. I've been so depressed the last week and I have 10 more days until I'm due and I don't think he will be there for his second daughter being born because he still is using and I really don't want him there. Any other single moms dealing with depression as they get closer to the birth? How are you dealing with it?

Sorry this was so long and thanks for reading.
