i have on occasion given compliments but mostly because they were obviously fishing for a compliment so I went along to make them happy. i wouldn't post it on an ex's fb or instagram or twitter account, because then it would make it look like i wanted her back or was pining over her to her and others. i have a few ex's that will comment on me and i just thank them or like comment or something.
When I tell the truth, it is not for the sake of convincing those who do not know it, but for the sake of defending those that do.
