@Katesev,
I read your post several times because I kept thinking that I must be missing something. I mean, there must be something good that you are getting out of this relationship to make you want to stay in it. But I sure don't see what that might be.
Granted, ending a relationship can be scary, but if you are not deriving any benefit from a relationship, then why stay in it? You can't be happy with the way things are, otherwise you would not be here seeking advice.
If your boyfriend of 2 years would rather run off with a bunch of friends on holiday instead of running off somewhere with you, then I think it time you ditched the guy. You deserve someone who will place you at the top of his to be with list.
