How do I stop worrying he’ll leave me?

Anonymous
We’ve been together for 2 years. He’s an absolute 10, gets so much attention from women. I’m a 7, at my best days. I think he’s with me, cause I’m convenient. His celebrity crushes look nothing like me, or what he considers beautiful. Lately he’s been going to places where beautiful women are, with his friends and I worry he will eventually get in contact with one of them and leave me.
