Am I overreacting?

So my baby is just under 7 weeks old and yesterday I asked my fiance for a break with her so I could get a little rest. I didn't end up getting one after he got home from work so I wanted to try during the night. I fed her and got her to sleep then went upstairs to bed while he took the couch next to her. She woke up shortly after so I had him give her some formula, but she kept crying. I had to keep getting up to try to console her and suggested he try putting her in her car seat on top of the dryer. I go up to bed, sleep for a bit then I hear him come up form the basement and she's still crying. I lay there for a while trying to let him console her, but eventually she is just all out balling with no sign of calming down so I yell down for him to bring her upstairs to me. No response, yell again and still nothing so I go down and he's fucking asleep. He just put her in her sleeper screaming her heart out and went to sleep. I don't get how he can sleep through her cries at all, much less go to sleep knowing she needs something. He doesn't seem to get why I'm so upset and feel like I can't really trust her with him when I'm asleep now. It already makes me edgy how he constantly falls asleep with her in his arms, twice nearly dropping her when he did and how when she wakes up and cries he won't wake up with her, but just letting her cry like that is something else to me. I feel like its kind of neglect. Am I just overreacting or am I right to be upset?
