I'm 10 months post break up, dating online successfully and am happyish. Am realising how unhappy I was with ex, and generally over it. Not pining over him at all. But today, a mutual friend mentioned him on social media and it really shook me. Just a cold, sudden sick feeling. We dont have kids so no contact is necessary, so I've managed to delete and block all social media effectively or so I thought. How do you guys cope with it or is it always that little lurch ?
