boyfriend and social media..?

[Lila]

Unfortunately, this might be a battle you can't win.
There are SO many ways for him to see or be in touch with or "like" his ex-girlfriends or simply comment on their lives/pictures, etc.

All you can do is politely state that you don't appreciate him "liking" his exes pictures because you feel disrespected and embarrassed and then ask him to please stop.

If he's a good guy, he'll stop doing it.

If he's kind of a jerk, he'll probably get mad, act defensive and keep doing it.

Then it's up to you to decide what to do about it.

Your boyfriend shouldn't be "liking" selfies of other girls ~ that IS disrespectful and really just childish.
Good luck!
