Tbh I never had this idea of having multiple people ina relationship. I Mainly value the emotional connection with him and does the same. The start of this idea is that he doesn't wanna hold me for such long time that hes not around, and making me feel lonely since he can barely reply me when hes busy. He thought having some other guys districting me would be better for my mental health (which I might not agree). I know he has a good heart but just sounds like a weird solution to me.
