After a year and a half together, Jackie and her guy broke up...but they kept hooking up. In fact, they've been hooking up for 3 years now. She wishes she could stop, but she says she can't. The last time they were together, he asked her to not see other guys and he said he wouldn't see other girls. She agreed, but she thinks he's not holding up his end of the deal. Jackie wants to follow him to see if he's lying. What should she do?
