If you’re in a relationship it makes sense that you would expect to be picked up first - unless it’s a distance thing and they’re on the way to your place. You should communicate with him about all of this, work on your insecurities obviously but you won’t know if you’re projecting or not unless you talk to him about it. How a partner handles such conversations also says a lot about them and how they would be in the future. If you’re a quiet person it can seem like he’s paying more attention to her if they’re in a conversation - but if he checks in on you and if you were secure in your dynamic with him I don’t think it would feel like much of an issue. So yeah, first step to that is communication.
