Husband isn’t being supportive

So I just had our second child about 3 weeks ago. With our first my husband was very involved and supported me very well and made me feel so good about what I had just done. This time around has been so different. He’s been all stressed out about anything and everything and making every moment about him and his feelings. He has to go to school in a few months and he somehow cannot choose to be present with his family and can only stress about that. I literally have been coddling him and his feelings the last 3 weeks trying to help him through it in hopes he might feel okay enough to be there for me in the way I need him to. He keeps apologizing and saying he will do better, but every day it’s the same thing. Absolutely emotionally disconnected. Today was my first full day by myself with our two kids and I actually felt relaxed and like I could rest. Isn’t that awful? Not sure what I’m looking for here but I just needed to vent. 😢

I really wish I could turn off my feelings and not feel so hurt.
