I am 24 and in the past I have experienced three times that once you bild your frame it's very easy to attract girls and eventually you find a girl for a relationship.

The problem I find is to maintain that frame. With a new person in your life, you start getting comfortable and reduce time on improving the frame as you get settled and over time your frame erodes and the relationships breaks.

Are their any books, podcasts or mindframes which provides insights into maintaining one's frame even after one start's a relationship?
