Wrong for leaving?

Heather

I’m leaving my fiancé and father of my child. I had my son 2/7...ever since his father barely helps out..& I been fighting post partum and he’s aware of it..lastnight we were supposed to go out (I didn’t bc I started having anxiety thinking about leaving baby)...he goes out doesn’t text to check on us once which pissed me a off a bit..& 3 comes around and he’s still not home his phone is off so I text his brother and his brother says he is passed out drunk on his mom’s couch...& I freaked out because no one told me and there was no reason for him to not be able to get home...we talked about him either Uber home or call me because I was just sitting home with the baby..the brother said it’s s fault bc he didn’t feel like driving him that far...am I wrong?? Like I would NEVER 1. Go out and never check on them and 2. get so drunk I can’t let him know I’m coming home or even 3. Get so drunk I can’t ducking get home to my family.
