answer:Yes. For your example, my best friend is an ex to whom I was nearly married. Had we not separated we’d likely never have managed to realize the wonderful relationship we have today. Granted it was a calculated risk. Furthermore, if you love someone, trapping them in a relationship to suit your own desires is a pretty poor way of showing it. And just because you let them go doesn’t mean you have to excise them from your live and vice versa. You, by-and-large, have to let people be who they are trying to change them frequently just brings even greater pain.
