How Do You Sustain a Relationship?

i like this for it to be sustained i like this idea of of so i think it's only in english and french maybe someone can correct me but i think it is falling in love també on a more in french. You don't turn the other person into the couch right like you don't turn them into just a piece of furniture that you are feel comfortable to youright? Like there's not a point where that's as vulnerable as i'm going right right and then like nope that's it right  that's not being vulnerable, I mean certainly in relationships you work out with somebody who needs a loan time or whatever they may need at the end of the day.
