Why does my ex's best friend want to date me now...

OK so my ex and I broke up about 2 weeks ago and his bff which whom he talks to pretty much everyday somehow got my number from someone (not the ex)... Show More

Updates:
The new guy even asked my ex after the very first time we met IF me and the ex were to break up could he try and date me and the ex said "i man I guess if she wanted to do that we would not be together so I can't tell her what to do anyway"
