Given I don't know much, it doesn't help. I am not a fan of cliche characters myself. I'm very much against them because I get bored, but to each their own. It's easier to leave the RP than bitch about someone else's char unless you have control.
Going on what it sounds like, he/she just doesn't like the idea of what they feel is 'cliche' and has a lot of contradictions.
I don't know your char or the RP, so, I don't know if it's justified, but sounds like one of those people who, instead of leaving on their own, rather bitch.
