14 years and counting

Lol, my real first bf at 14, had our daughter at 18, still together at 27. He is 2 1/2 years older than me.. we have been through everything together but yet we still arent married. He has asked twice and twice i said yes and twice it was called off. Once by me and then once by him.. i would love to marry him. Especially since its been 14 years. He is the love of my life but im starting to think that maybe my dream of marrying him may not come true.. im mean come on he is 30 now.. he has loved me since he was 16.. We r ttc, but yet still no marraiage talk in a while.. srry for the vent idk what to do anymore.. maybe i should walk away.. any advice?
