I think the MC actually went above what most guys would do. Without a relationship he did tell Maya he was going home for a girl. He could have said it was just to see his dad. Also, he tells Josy he is staying with a girl.
About the second, i think that It's way different. Maya thought she just liked girls, It happens. Happened with a friend of mine in real life. For most of high school she was a lesbian. In the last semester, before going to college, she had sex with a guy just for curiosity and nowadays she can't hold a relationship with another girl for more than six months because she miss sex with guys.
