Am I right not to be with her?

Socially I'm old school and I would only want to be in a long term relationship with a decent girl. By decent I mean good morals and not dirty or nasty.

So my current girlfriend who I really took seriously as far as to meet her parents and treat her right. We've been together for 2years already. Just yesterday night she was going to film herself touching herself.

I ended up telling her that changed my perspective on her and I thought se was a decent girl and I wouldn't really want be in a long term relationship with her anymore.

The conversation ended there and I haven't talked to her since yesterday night.

I really wanted her to be the girl you know but after this I'm considering breaking up altogether. What are your thoughts on this?
