Lost my baby

I delivered and lost my baby on April 11th I was only 22weeks but I feel like I’m in this alone my child’s father left me in the hospital alone the night I delivered our baby then came back the next day to pick me up with his other babymama in the car I asked him to stay with me last night because I didn’t want to be alone again he gave me an excuse why he couldn’t but I later found out that he was with another female last night instead of being with me I told him how I feel and all he keep saying is we grieve different and how he does care but his actions show otherwise now he’s just ignoring me i just feel like my life is over idk why this is happening to me I think it’s some kind of karma he keep telling me we’ll try again but he’s not even trying to be there for me now I do want another baby with him but I’m starting to think it’s for the wrong reasons now just need help on how I should handle everything
