Ex and social media

[Pinkflowerpetals]

I recently found out that my bf is liking all his ex's pictures on social media including bikini ones, I have expressed my feelings on the matter and he says im being over the top about it, and thinks im crazy to cut the matter short, it keeps niggling at me, he says he doesnt have feelings for her and they were over a long time ago, am I being unreasonable?

It’s a bit strange; the odd one would be fine but is it literally all of them?

It depends. Are they still good friends? If so then it's not completely unreasonable (but would still make me uncomfortable), if they're not in contact much and aren't particularly chatty then I'd say it was odd.
