My friend didn't know he was married. See, they use to work together and now they both have different jobs but my ex lied to my friend saying he was single and wanted to know if my friend knew anyone he could "hang out" with. So my friend told him about me and than we started seeing each other. I knew I shouldn't have slept with him on the first date but I really liked him and I thought we clicked. He even said we did. Heh... what a liar.
