Fiancé doesn’t help with baby at night

I’ve heard all about resentful moms pissed at their partners for sleeping through the night while baby fusses but at what point is it a red flag?

My baby is 3 weeks old and she was up all night fussing. She hates her bassinet and just wants to sleep in my arms. So I was up all night putting her to sleep over and over again, dealing with spit up, and burping her. I ended up falling asleep with her in my arms accidentally because I was so tired. My fiancé woke up each time she fussed and went back to sleep each time. Yes, I’m the only one who can feed her but a lot of these times she didn’t want food. She needed to be burped, she had just spat up, or she just wanted to be held. He could have definitely done something to help me those times.

One time I was just soooo tired I asked him to go make her a bottle and he got up and took her and fed her. So he helps if asked.

Finally at 6am this morning I said screw it and woke up with her even though I had basically no sleep and he saw me wake up with her and went back to sleep. She then cried for a while while we were downstairs and he got up, checked on us and then went back to bed because he’s “so exhausted and can’t keep his eyes open”.

I’m just so infuriated. He always complains about how tired he is yet gets 7 hours of sleep every night while I get maybe 3 spread apart if I’m lucky.

Is this normal?
