My fiancé doesn’t love me.. & I think I’m okay with it..

He has never really showed me that he loves me in any way, I just sort of assumed he did because he says it when he says goodbye. He proposed, but that’s because we have a daughter together and a son on the way. We don’t really talk about things and he never calls me beautiful or anything like that. Will only tell me he appreciates me if I say it to him first. Only kisses me back, never initiates the kiss or sex unless it’s just head (and only for him). He’s not abusive or anything, not even emotionally. He’s not really anything.. but it’s okay. We live a comfortable life. I’m happy & my kids love me so I guess that will have to be enough 🤷🏻‍♀️
