Is my girlfriend trying to make me jealous?

My girlfriend of 6 months wears really cute clothes, also revealing whenever we go out, she has a really gorgeous body, but I dont say anything about it because she is way out of my league and I dont want to lose her.

The thing is whenever she talks to anyone, she is really touchy, also guys, which is my issue, and also doesn't seem to mind the guys checking her out, and her cleavage.

It really makes me jealous, but I dont want to tell her so directly, what do I even do atp?
