Wasn't sure how to word this exactly, but who went through the most love interests as in that they either had lots of flings or lot's of short lived relationships with not long in between one ,ending and the next one?
Mason comes to mind in recent times. He never got into a solid relationship. He had the chick who outed his family being in witnesses protection, then the casual friends with benefits with Evie. Then Olivia on the rebound then the girl who died that wasn't with long before that happened, then the girl he got pregnant who was just a fling. He had a thing for Jasmine in there somewhere too.
Then there was Ash who went from Danny to Phoebe to Kat to Tori and I think they all kind of overlapped. He had things for the next one while still in a relationship.
