When is it right or wrong to send a Facebook message to an ex?
Had a brief (3 months) but intense relationship with someone 20 years ago. We ended on bad terms as in he took my decision to end it badly. I was not in the right place to be entering a serious relationship which is the way it was heading and he didn't respond well to me ending it.
Looked him up on Facebook and whilst I harbour absolutely no romantic feelings for him whatsoever I would love to say hello. I can see that he is Facebook friends with his ex wife which is a surprise because the split wasn't amicable but they've both moved on I guess. I don't want to be his Facebook friend I just want to say "hi, glad you're doing well" because I am genuinely pleased for him and I also really liked him a lot. Is it really bad form to say "hi" to an ex on Facebook?
