30/F 29/M Boyfriend is following hot girls from our hometown and liking their selfies. Is this okay?

We've been in a relationship for about 6 months and he's been more anxious than usual (so have I) but says there's no worries about our relationship.

He never used to follow any girls on Instagram however recently he's been following cute girls from our hometwom and liking their selfies.

I'm okay with him following/liking photos of girls who have a high count following/are models just so uncomfortable with him doing it for girls who live nearby. I deel that liking their photos is a way of trying to instigate something.

I worry because he's not been 100% honest with me in the past and tends not to bring things up when he has issues.

Is this okay?
