Put a ring on it

I know I'm a little young to be talking about this and all but I've become curious about this when me and my close friend started talking about it. 
My best friends parents have been together for 15 years and have been engaged for 10 of those years and they're still as happy as ever. I realised as a little girl I dreamt of having the perfect wedding but now my opinion has totally changed. I feel like a relationship is expected to lead into marriage but I'm just wondering if anybody else has the same opinion as me. do you guys think that marriage is necessary to have a healthy relationship?
