will I get married and have kids? I am a tiger and he is a rat.

I have been in a relationship with the same person for 12 years. He doesn't like to discuss marriage or starting a family. Sometimes I think he's right for me and the other part of me fills like I'm just in the relationship because it's a comfort zone and the amount of years. I don't think he will marry me and I feel like I'm wasting my time.
