Help me understand,cheating?

Hello.

I am unsure of what to feel? Can you help me understand.

So I was on my Facebook scrolling, I saw that my BF posted these comments on two different females

They’re independent artists.

So it’s no one we know personally.

My question or thoughts are:

Is this cheating ?

Should I feel a little discomfort?

Why do I feel like it’s a big deal?

I know it’s ridiculous to ask this when he doesn’t know them personally and when he just complimented them.

That’s why I feel stupid for asking and feeling a certain way about it.
