My point is that the MC is NOT reciprocating. And while the MC CAN tell the girls about his feelings for other girls, he NEVER does, not even in that phone conversation with Josy; 'seeing other girls' is not the same thing as having feelings for any of them, not the kind of feelings he is developing for both Josy and Maya.
Not only that, but
TanusMorken has pointed out to me that Maya DID tell the MC that she had a girlfriend. How much more completely honest did she need to be? It happens during the conversation the MC has in Episode 3, when he returns to Maya's dorm room after spending the night with Jill.
Maya: "I've dated guys before... ...but I've never slept with one."
MC: "So, you're a virgin?"
Maya: "...no."
MC: "Oh...you mean that you've..."
Maya: "I've only been with a girl, so far."
MC: "But...what about...you know..."
Maya: "You and me?"
MC: "Yeah...?"
Maya: "It beats me... It's the first time I've gotten this close and felt this kind of attraction to a guy..."
MC: "Is this what you've been hiding?"
Maya: "... I can't complete that list on my own. And I shouldn't complete that list..."
MC: "This might be a long shot... ...but what if you told them where you come from?"
Maya: "And tell them that I've only been with a girl!? Are you insane!? No way! No fucking way! I'm not telling anyone that! Nuh-uh! Not again!"
MC: "You told me..."
Maya: "Don't tell anyone... Ok?"
MC: "Of course not. Is this why you have family issues?"
Maya: "It's that obvious, huh?"
MC: "I'm just trying to connect the dots here."
Maya: "Yes. That's why. My family is...um...well my dad is... He's very religious... And when he found out I had a girlfriend...he..."
MC "Oh...say no more...I understand."
Maya: "Ok... So...now you know. And please...don't tell anyone about it."
Maya is certainly more honest in that scene than the MC ever is.
I understand that some don't think that Maya has been honest with the MC. But that doesn't mean that their opinions have any validity or any basis in reality.
