When is giving your love enough

I'm 16 and 🙍🏽 I'm loving somebody who's not giving me enough of what I need (not sex) just him and his love and loyalty but I'm constantly enduring everything because I love him and .. I know it's not okay or right but I just want him to grow up and realize Iv Been here longer than those other females and he thinks i don't know about his side girlfriend but i don't want to say anything because I love him 😴 and I think it's hurting me more than it is him. I just don't understand how somebody could make me feel so worthless but beautiful at the same time? Am I not enough? Somebody explain and just help me figure out what I need to do to do right by me this time instead of him.
