so if i have this correct, the "nice" guy broke up with you for two weeks and hooked up but didn't have sex? as a guy I have to tell you the liklihood that he didn't have sex approaches zero.
maybe you secretly want to get revenge on your boyfriend by hooking up with an old flame just like he did? have you considered that?
you sound a bit like you are addicted to drama, but truly desire something more, something deeper, and real. its good you want that, keep seeking it and you will get it.
you have to start letting go of your need for drama and begin to embrace you desire for something deeper. what exactly do you REALLY want in a relationship? how would it look and feel and be? think about those things and then make them happen. let go of the bad boys and the drama and all that begin to imagine a real life for yourself.
how old are you? you sound young. you'll have these kinds of things at a young age. but dont - DO NOT!! - get pregnant by a jailbird!! ok? you hear me???? DO NOT DO IT! you will regret that for a lifetime! it will be nothing but heartache pain trouble or worse. pandora's box, thats what that is.
