Depression is kicking in

And its bittersweet I love my baby soooo much I've never been happier but I know my relationship with her father is over and done with and Im just so confused do i stay and cry myself to sleep every night for her sake or do I leave . hes been emotionally absent for a while now but works hard to provide financially. we don't even talk anymore and when we do I feel like hes being sarcastic and rude. He wasnt there for her birth and I cannot pray hard enough to forgive that. Im so lost . sex is not a concern for me anymore I never have time to do anything can't work because he wont watch her to make me have to depend on him and be mistreated. I just want him to love and actually be concerned about my baby's well being.
