This sounds like a classic case of a guy in the friend zone who gets called to do random favors in hopes that maybe if he's nice enough to her he'd get laid.  I see two things happening to this guy...  A: he gets bitter and join the red pill mra movement talking about how he's such a nice guy but bitches only use nice guys and fuck the assholes so now he's going to act like an asshole... Or  B: Gives up on getting a pretty shit lady and starts fucking whales.
