My girlfriend [26/F] for 5 months broke up with me [27/M] 3 days ago. I'm feeling lost, miserable...in hell.

We had no fights, a very good relationship. I did not see this coming and i'm lost, with my head still spinning.

She broke with me 3 days ago, reason being she wants her life before the breakup back, she thinks that she is still not ready for a serious relationship (both of us already had long relationships 5+ years). I'm still love her, a lot, more than i ever loved anyone. She was the most beautiful girl that i ever met and we got along very well...and I'm having serious doubts if I'll find someone like her, ever.

She said that, about 15 days ago, she realized that she doesn't want the relationship anymore ...she hid her feelings all these 15 days until the breakup. I'm thinking that is not fair not to give a chance to this relationship. The first time she had talked about it was when she broke up with me. She said that there is nothing wrong about me, it's her fault, her whises, that she cannot lie to herself and that she doesn't think that it will change (the old "it's not you, it's me"). These 5 months were incredible, best time of my life, no doubts, it's strange that all of this vanished in 15 days...

I'm applying the NC rule, but as everybody knows it's tough as hell to do that.

I'm pretty sure there is no infidelity involved.

Sorry about the bad english, i'm not a native speaker.
