ex girlfriend...help....

hi...I had a "friend" but we were moe like BF and GF but...2 weeks ago there was a stupid problem and she decided to end things...she is a very proud, dedicated, and any desicion that she makes is like lie or dead desicion...I really love her and i bought a diamond ring cause i want her to be my girlfriend...but i bought it before everything happened...i putted the ring inside a book that she likes and i want to give it to her as my last hope to be with her...if she says no I will forget about her. I know I want to do this and probably I will do it, but just want to know how other people think of my situation
thanx
