"I understand that I'm not all she wants but I will make myself pay for not being her everything".

That part worries me. Don't do anything to make yourself "pay for it". This is both your problems not just yours. If I were you I'd consider counseling for the both of you and get down to the bottom of this. And the thoughts of her finding someone else is a rational feeling I believe. I would probably think the same. But from lack of detail in your story, she probably hasn't found anyone. I to have a problem with codependency so I imagine this separation will be hard for you. During your break you should do exactly that, a break. Don't overbear her with texts or calls. Just let her have her time and then she can communicate that with you after the separation. You're going to be lonely I'll tell you that. Keep posting here if it helps.
