You are already playing house
You live together. You have children. You share bills. You cook, clean and wash clothes. Sometimes people even assume you are married although he still tells people you’re his girlfriend. You have essentially taken on traditional wife duties without the title. Why should he get married?
He’s already said no, you’re just not listening
I’m very serious about this. Many guys, early in the relationship, have straight up said they don’t want to get married. He said something like: “Marriage ain’t for everyone!” or “My parents weren’t married and I’m doing well!” Or maybe even, “No, Jennifer, I’m not interested in marrying you.” But you persisted, thinking you would be the one to change him. Please keep in mind that no amount of love can make someone do something they don’t want to do.
