Most Helpful Girl
Not to be a dick or anything, but you said you guys are starting to drift apart, and nothing is the same, but youv only been together for a few months.
Anyway, honestly (not trying to be a dick again) it sounds like you guys are being high schoolers. You might or might not be, but this going back and forth (from you and her) saying things like "break" is kinds dumb, especially if youv only been together a few months. If you guys get along, that's it. If you dont, then you probably shouldn't be together. Its early enough in the relationship that IF you do break up, it won't be the end of the world.
Blocking her, and her saying your just a friend, is stupid.
My advice for you: you need to stop with the blocking or any unfriending. Take electronics and social media out of the relationship. Allow her to do her business (her life/friend issues) by herself. Be there when she needs you to be. Be kind to her every day. If it doesn't work out, that's fine too. But just dont go back and forth with her. It's dumb, and childish.
