3 weeks and nothing seems to have changed?

I dont know why but the past couple of 2-3 days seemed fine to me, i barely even thought about her and i thought i can finally move on it was a 4 month relationship she dumped me out the blue and i begged her allot but she didnt want to be in a relationship.. So i went NC i have been for 3 days, and i dont know why, today is my birthday but i miss her so so much i just dont know if ill ever find a women like her in my life again, she was so kind, funny, and loyal, but she had some really weird things about her that made me question her existance... Im so attached i dont know what to do im crying right now too
