Married but feeling like a single mother

This is the message that I sent to my husband and I feel so bad and guilty for feeling this way but this is just honestly how I feel. My husband does not do anything. Everything about our kids and house chores is on me. I love my kids with my whole life but I feel like I’m at the point of a breakdown. My husband is a good husband and I would marry him over again if I could but I wouldn’t want another child with him- I just don’t know how to explain it.
