It sounds like your bf likes being over dramatic. Usually saying "we're over" does mean exactly that; so if he says it isn't then I'd feel as if he's trying to make you feel bad, rather than actual wanting to solve whatever problem it is. You need to sit down and talk properly, maybe a little at a time, when you're not arguing - which s easier to say than do.
Meanwhile, stick with whatever your heart and mind tells you to stick with and hang in there. If it's worth fixing it's worth trying from inside the relationship first.
Just remember that there are a lot of people who care for you.

He sounds far less mature than you. "We're over," unless he was on stage, means it's done. To use that as a weapon or to toss it around without meaning makes him unpredictable. You don't need that crap.
I agree with what Barium said, it sounds to me like he's playing with your emotions and holding the threat of him leaving or your relationship being over against you. I think you're better off without someone who wants to control you like that, because that's really what its about. And those tickets to Vegas? Why would you want to go there if you're fighting and hating each other? If his mom wants to be angry at anyone for the cost of the tickets, its him for messing up his relationship, not you, you're the victim here.
