Ex girlfriend hasn't spoken to me for 5 weeks. I never showed her enough attention & maybe didn't put her feelings first all the time.
We both got drunk one night & ended up having an Arugment, not seen her since. I heard she's book holiday on her own, the one we weren't to go on.
Is it over?

Yes it is over.

yes it is over.

Even if I know she still loves me, she's a very stubborn girl.
We were planning a holiday & before I know it were over..

You don't know a good thing until it's gone. Learn for the next relationship.
