Amazing relationship completely falling apart after baby

My husband (31M) and I (27F) have been together 8.5 years and married for 2. We have an almost 9 month old. She wasn?t planned but we were so happy to be parents. She?s honestly a fantastic baby and just the most amazing thing ever. But ever since I gave birth my relationship with my husband has just slowly been falling apart.
I don?t even know how to describe the change. But we went from being perfectly in sync and loving to now having an awful time communicating. He?s pushed me away any time I?ve reached out to him for help, saying I should ask someone else or learn to be an adult. When I ask for help he?s asked if I?m asking for myself or asking for the baby. He?s had multiple overnights away since she?s been born, either to visit friends, go camping, or for work.
He tells me I can do the same, that I?m allowed to ask for time to do fun things, but I can?t ask for his help when things are hard, so how can I go and ask for his help when I want to do something fun? I feel like I?m always doing something wrong, like I?m never good enough for him. I tried opening up about my self image/body struggles postpartum and he said I was being too negative. He says I only talk about the same things over and over.
We used to share everything. We had a relationship all our friends and family admired. Multiple times he would surprise me with homemade picnics, day trips, dinner, coffee. He told me I wouldn?t be forgotten once the baby came. Now he?s upset any time I have a need. He says he has to have infinite energy for everyone and everything around him, that he doesn?t matter.
He goes for bike rides, hikes, sees friends, plays guitar, writes, knits. I always make sure he has time for his activities. He says I can do what I want too, and gets upset when I don?t, but if I take time for myself will I be called childish again? Will I be told I?m not really an adult and I don?t know how to be responsible?
I know he?s stressed. He?s working and I?m at home to save us money and am also going back to school full time.
He got me tickets to a concert for Mother?s Day, but the concert wasn?t until October. When we went he was on his phone checking on our daughter. I didn?t know, so gave him a look, and he yelled at me that he was trying to be responsible and make sure nothing happened to her.
Idk, I know this is a mess. I?m sorry. I?m trying to get us into couple?s therapy but every therapist either doesn?t take our insurance or has cancelled on us. He just started with a new therapist on his own, and I have mine as well.
Tl;dr my relationship is falling apart. We used to be perfectly in sync and loving, but since having a baby it feels like he resents me and just doesn?t like me anymore.
