@sammy29 It’s been about 7 months since he broke up with you. That’s plenty of time for him to have tried to make amends and reconcile. You should know that long distant relationships are very difficult to maintain! Sooner or later most people give up trying.. How far apart are you?
Does he still have a girlfriend?? He might just be bored/lonely and that’s why he chats with you on Facebook or Instagram. I suggest you avoid the social media sites for a while and see if he initiates contact.
How long was the relationship and what reasons did he give you for the breakup??
