it's not persistent you want. that means anyone that keeps trying, which means they disregard your feelings and desires, goals etc.. will win in the end.

you want the opposite not someone that thinks that if they keep pushing they will break you down but someone that actually cares for who you are and to give you what you want and need. that's what a relationship is all about and what loving someone means, his goal is he wants what he wants and his goal is not about you it's about what he wants and is entirely selfish.

keep that in mind when you feel weak.
