The lover went to the circle of friends to comment on his girlfriend's remarks, deliberately letting me see them.

First of all, you should know your lover's personality.

If he is a careless person, maybe he didn't think so much and didn't expect you to pay attention to this comment.

It is also possible that he is a very calculating person, so he may deliberately let you see that there are other intentions.

In short, if your lover is not loyal to you, don't be too nice to him, and be ready to get out.
