Found out my bf is a con? now what?

4 months ago i began seeing this guy so far everything has been great. He is so nice and attentive and shy Until last week we finally moved ped just kissing. then he disappeared. 5 days later i couldn't take it i sent him 2 text messages asking what his deal is. A friend suggested that i should google him to see if he has a facebook and maybe see what has been going on...i did and found out hes married with 3 kids and has been arrested and called a con he has had several jobs which he gets fired from due to stealing and from job finding out that he was robbing homes!!!!!!!!!!!!!!!! He still hasn't texted me which is weird because he would text everyday i dont even know what to do? should i let him know i know? trust me i know its over? but ive been conned!!!!!!!
