Advice from moms with partner not helping with newborn

So I know it’s sadly more common than it should be, but moms tend to unequally do more newborn care, whether they are breastfeeding or not. Moms tend to be more realistic ahead of time about how difficult and exhausting it will be to care for a new baby. And it can be really hard…. That’s where I am now. I really need some advice from moms who had a newborn and a non supportive partner and how you dealt with it. I need support and advice of how to release resentment and how to cope and not miss out on enjoying my time with my baby because of the inequality, resentment, loneliness, postpartum hormones, and lack of support system. My baby deserves better 😔. I am talking to a therapist and have anxiety meds but it’s still so hard. I want to be ok on my own and feel like a healthy mother who loves caring for my baby. I didn’t know that these feelings would get in the way. I want to remember this time with my little miracle as beautiful, and it feels anything but that. Working on the relationship or him changing is not an option right now due to two people needing to be willing. I can only change and focus on my own behaviors and thoughts and feelings during this time, and the long term I will have to think about later. For now, if anyone who has been there has advice, resources, word of encouragement, etc… that would be so appreciated. I’m open to anything ❤️
