The best way to break up with her would be some where in a public setting just in case she doesn't take the news to well. If you want a chance at getting back with her later then you should say these exact words, "Look I'm not interested in continuing this relationship right now. So we are done, but if I fail at finding a better woman I'll get back with you. Understand what I'm saying?". If she has low self-esteem ,and doesn't know her worth as a woman then she will agree to this and wait for your return. Just to be extra safe dawg make sure there isn't any sharp objects around when you tell her this.
Maybe if the op crazy enough to say it he'll be the first.
