idk what to do....

so I moved in with my ex almost 2 years ago. And we've been off and on. but I don't know if he's the one I want. all together we have been together for almost 5 years,,but he doesn't want marriage or kids and I do..mind you too we have a age gap....14 years to be exact. but I feel like he doesn't treat me like a gf or even a wife in the future. I feel like I treated like I did when I lived at home and I'm worried if I stay it will only get worse..i mean I love him but then there are times he turns my love completely off for him and I don't think he notices it..idk what I should do..i don't think he wants what I want and if we try to talk about it, it just ends up in a argument...i just don't know what to do anymore...and usually I give the best advice to friends but I can't help myself...any advice.
