<human>: Summarize the given text in a few sentences.

I have been in a somewhat romantic relationship with this girl for 6 years, there's kissing, there's petting, and other things like that. 

After the first year she has refused to date me, and she won't tell me why. I suspect it's because I eat meat, and she is a vegan.

Is she in the right for doing this? I know I shouldn't have to change just to fit her standards, but I don't want to lose her.

There's clearly a sign of attraction and affection from both parties, but she won't be my girlfriend and she won't hold my hand either.. We don't do anything in public near others.
<bot>: Girl I have been romantically involved with for 6 years refuses to be my girlfriend, probably because of a personal choice which shouldn't matter. Help?
