Should I be worried about my boyfriends new female work friend?

My boyfriend have been together for a little over a year, we have had rough patch where he did try to hookup with another girl but we broke up for a couple weeks and did not talk during that time. Since then, we got back together and I have had major trust issues with any girl he talks to and that causes a lot of issues as well where he feels like he can’t have friends. He makes friends easier with females than males, I know it and it never bothered me until the instance of him asking a girl to hookup. Now recently we had a big fight where he doesn’t think he can do this anymore if I don’t try to trust him. I’ve been trying but what has bothered me is that he met a new friend from work. She’s a female, a little older than him and looks a lot like me. Okay, that’s not a big deal. But what bothers me is she requested him on Facebook at almost 11pm and has nobody else from work on her Facebook (yes I did snoop). He accepted her friend request and from what the information he has given me is that he mentioned something about her car that he noticed was broken. He’s a car savvy guy. But me being me I added her on Facebook to assert myself as “the girlfriend” since it’s 11pm she added him and she has nobody else from work. Should I be worried?
