i feel like he's stop caring about me, doesn't say cute things anymore, i feeel like he doesnt want to marry me or have kids.. I don't know i can't tell what he wants with me in the future . i mean is 3 years a good sign that he wants to be with me?

he says he loves me and stuff, he works a lot to try to get a place for us together soon. I mean i don't know what else am i asking for . he's sweet and tells me when i need anything when i'm sick. idk how can you tell the person your with wants to be with you?😖
