I feel my heart sink every time I see my girlfriend liking other men’s photos

DEAR DEIDRE: I FEEL my heart sink every time I see my girlfriend liking other men’s photos.

I’ve asked her to stop so many times and she says she will, although she sees nothing wrong with it.

She says these men are just friends or colleagues.

I’m 33 and my partner’s 31.

We’ve been together for four years.

Even in the early days of our relationship I noticed she was constantly looking at other men when we were out on dates, which she denied.
