Is my partner in love with his best friend?

Well there are several ways u can look at this. I dated a girl but I never fell in lover with her bcs I was in love with my best friend. I met her freshmen year and we didn't date till the end of my junior year. Were out of highschool not and going to be married. But seriously enough about me. If he truly means what he says about just being friends with her then id listen to him. Trust me if he wants another u would know for a fact. I hope this helps
