Ok lady's is wrong for me to be friends with ex. My boyfriend get bent out shape every time he say hey to me on Facebook or instagram my ex know I'm in a relationship an he respects that an would never over step his boundaries. My boyfriend got very upset cause my ex made joke about our son look like him and told not do that an he apologized about but like boyfriend hates him for no reason an his really sweet person it just we didn't work out an both move on an are happy an just want be friends is so wrong
