Wifes severe depression, MLC, and suicide attempt

[Lifes Twists]

So yesterday my situation got more difficult. My 18 daughter showed up at the house with his parents. I was to find out she is pregnant. I asked that my wife be called and asked to come over so she could find out and we all discuss it together. She did com over and in the process made a few comments to me that leads me to believe that she feels I am blaming her for this. The boys parents had a lot of wonderful things to say like how my daughter can come live with them, etc. This boy will be 20 next month, quit high school so has no diploma, and is not working. So his parents are blowing smoke up my daughters a## and leading her down a bad path. My wife won't communicate with me and I feel like I am going to have to go this alone like usual and be a bit of the heavy. My daughter and his parents have to understand that I am in no way able to help her financially. I am upset that she will probably give up her college ambitions because of everything his parents are verbally telling her right now. I am also upset that I had a partner in bringing her into this world that has now checked out really.

Not sure what I should or can do.
