I am learning Shmuel A and the Maggid Shiur (Rav Aron Chaim Lapidoth) mentioned (I forgot the source) that the Navi calls Dovid before he was Melech as “Admoni” same adjective lehavdil to Eisav. He pointed out the contrasts between the two. THen he said that Dovid should have been Yaakov Avinu’s twin. In that case, Leah would have married Dovid. THat’s why she was crying so much.
