I'd never dump someone just to go after someone else. Something would have to happen, we'd have to have a fight, or it must become clear to me that we aren't compatible... etc. I'd never be happy with my girl and then dump her because I want to go after another girl. There would need to be a reason just between us as to why the relationship needed to end independent of any other person.
I didn't even need to look at the pictures to know that my answer is no.
I would never dump any girlfriend for someone else based exclusively on looks. I don't care how gorgeous the other woman is. If I'm in a relationship and it's going well, I'm not dumping my girlfriend for anyone else.
