PS Anytime anyone asks if they should break up, 99% of the time the answer is yes...

Why?

Because when you're with someone, you should KNOW that you want to be with them. You don't show that. In effect, you're giving a bunch of reasons to stay with her that don't amount to a pile of beans. If a guy told me he stayed with me for a long time because it was easier than breaking up and having to tell other people (as opposed to simply wanting to be with me) then I'd want to punch him.
