Husband doesn't wake up

So my baby is 3 weeks today, my husband told me I should go hang out with my friends for alittle because inhave been sitting in the house for 3 weeks. And he was going to watch her, I told him she has to eat in 2-3 hours (I had some breast milk in the fridge for him) it's my first time leaving her. I go down to my friends for alittle i try calling him about the time she needs to eat no answer I call/text a couple times, so I leave early. I come home he didnt feed her and he is asleep next to her while she is screaming. I am so mad right now, but also learned i dont think anything at night or where he is tried he cant have her by himself. Anyone else have this problem with there husbands being a heavy sleeper?!
