Throughout its nine season run, Ted, the main character of 'How I Met Your Mother' has racked up quite a count of ladies. Not as much as the playboy Barney Stinson, but impressive enough. He's been in relationships that have lasted years, rekindled things with old flames, been head over heels in love and had a few one night stands as well. Here's a list of all the women he's dated, until he finally finds the real deal with the mother.
