Male coworkers wife asked me to stop liking his pictures on instagram?

I have my male coworker on instagram. I’ve met his wife before and she seemed she didn’t like me, or was jealous of me.
I sometimes like my coworkers pics on instagram. Today, I got a random message from her asking me to stop liking his pictures please.

Should I stop liking them or ignore her?
