So how do relationships fall into place?

im becoming very at ease with myself these past few months and feel like im becoming my true self, self acceptance is what i mean. now that i have accepted myself and love myself for who i am, i think now i should be ready for a ual relationship. do u feel as if everyone who has successful, long-lasting, positive relationships has to love themselves before they can maintain an intimate relationship? my confusion comes over how i ws talking to a girl last night who has a bf and we had been talking very openly about , not personal experiences, but just ual jokes. is it normal for a girl with a bf to joke like this with other guys? i talked to her today and it felt platonic but the other day it was a turn on being around her. any insights as to how my situation is unfolding?
