I feel so depressed.

What did I do to deserve a man to walk out on me & his baby I never pictured my life this way . It's been 8 long & emotional months tears that could flood the ocean Iam such a good person why did he walk out on us 😞 How will I tell my daughter her dad can't grow up & settle down . Sometimes I feel like it's my fault were did I go wrong ... I did so much for him & put him before anybody while all he did was use me .
