all we gotta do is be brave and be kind

I have questions.

Here's the story.

I work with my boyfriend. And no one there knows that we live together or are even dating. So a while back this girl worked there. She's a smiley, tiny, young, blonde girl. And everyone flirted with her. And i felt my boyfriend do it too sometimes. And it bugged me. But we were at work so how could i say anything? So fast forward to months after she left. He had her on snapchat, and would look her up on FB. Now let me make it clear that i do not think he would cheat on me . I know he would not do that to me. But we all know me. I'm very insecure about myself because of my awful skin. So when i noticed that he would look up her Facebook, send her chats and snaps it bugged me. So i told him. He deleted her on snapchat but still looks up her facebook. It bothers me when i go to use the computer and see that he looks up girls facebooks. Girls we work(ed) with, friends of theirs. AM I WRONG for being upset? Am i over thinking it and having tendancies of a "crazy girlfriend"??

I dont know what to do but its definitely creating a rut in our relationship. I just need an opinion. I don't have anyone to talk to about this kind of thing since mostly all my friends work with me. 😔
