When guys are different with there friends than there girlfriends which version of them is the real them?

Im with a guy and he’s more masculine and likes to show off with the boys even when I’m around but then when it’s just me and him he’s a different person he’s more sensitive and vulnerable. I don’t really like the version of him when he’s with his friends he comes across a bit like an asshole if I’m being honest.
