I think you are overreacting based on what you’ve written. 😳 It sounds like you’ve just learned that his ex-girlfriend is in his circle of friends and that news unsettled you. Other than that, it really doesn’t seem like he’s done anything to disrespect you or denigrate your relationship. His going to the bonfire without you seems like a one time incident that doesn’t require you weighing it heavily. Sometimes these things happen without prejudice. He doesn’t seem to be avoiding you or keeping you away from his friends and family in any meaningful way.
What I can tell you is that it’s in your best interest to keep things light and not create problems with his friends and family. If you make it okay for him to continue his friendship with his ex-girlfriend’s brother, then there won’t be drama surrounding you. You may be in love with him, but remember, you’ve only been in the picture for seven months and his best friend has been around a lot longer. What you don’t want to be is a nag who demands to be first and foremost. What you DO want to be is the girlfriend he wants to have with him, show off to his family and friends, and to be able to enjoy alongside his friends, too. 😀
