This sounds like potential ppd/pp rage, I would reach out to a therapist or your midwife for a referral to one. It's not fair to your husband (or to you) to have to walk on eggshells to avoid even small confrontations. You don't want it affecting your relationship long term if it continues so I would seek help sooner rather than later to get some coping tools for both of you.
I’ve also seemed to be taking out things on my husband as well. He says that he gets it and that he knows it’s not personal. Personally, I have hit my limit and don’t think it’s fair to him or me so today I signed up for better help.
