Is there any chance to get him back, im cryingggg :'(?

no dont get back with him he has no right to make you jealous. if his treating you like this now imagine thank god he showed you his side dont waste your time move on he has no right to do what he said. & if he diddnt want to meet your family meant he was not serious because if his serious he would be happy to meet them.!! so am sorry to tell you this but dont try i now its hard cus your proably have feelings for him but be happy it diddnt happen more far along. (: good luck!!
