should I be jealous?

Riley β€’ Gay, stressed, and well dressed
So I'm away at college but my girlfriend is still back home. She called me yesterday and told me that she had given her friend Allura a hickey. I know it probably didn't mean anything, but should I be upset? I've been cheated on before so maybe I'm just paranoid? Advice please πŸ™πŸΌπŸ™πŸΌπŸ™πŸΌ
