Are all men assholes after having a baby?

I’ve been with my bf for 5 1/2 years and we have a two month old daughter together. Ever since she’s been born it’s like he is a whole different person. He consistently always has an attitude toward me no one else. If I say anything of any kind his response is always in an attitude. If I say anything like “be careful when doing this or that” his response is “ok mom I didn’t ask for your help nor do I need your opinion”. Then when I ask why is he so rude he says ever since the baby I’ve been overly sensitive.

But guys I have never felt so unhappy in this relationship until now. I’m sure my post partum depression plays a role in it but idk if this is something all couples go through or is my relationship just coming to an end?

I’ve cried myself to sleep many times and he doesn’t even care. Just completely ignores me and goes on his way. I just don’t know what to do anymore.

Update: let me rephrase that part when I say “be careful doing this or that”. I don’t mean it towards his parenting skills I say it towards everyday life activities. Like today we are suppose to take his brother car to the auto shop at noon and it’s 9am and he been drinking all night so I asked if he was going to bed soon and to stop drinking since he going to drive and that’s when he got all rude with me saying he didn’t ask for my opinion.
