Broke no contact. I am such an idiot

I broke no contact today after 3 weeks, and I regret it so much. I feel like I just reopened a wound and it hurts so much all over again. I am so stupid for doing this to myself when she was the one who broke my heart to begin with. I texted her asking how she had been doing since we broke up and when she responded, she just seemed so different, she just seemed cold and like she never liked me in the first place. She told me she's been doing good and asked how I've been and that she thinks it's better for both of us we broke up. I feel so hurt all over again, and this time I have nobody to blame but me this time around. I did this to myself.

I am never reaching out to her again, I learned my lesson the hard way. I realize now that I can't make her care just by caring more. I threw away my self respect and I feel so embarassed for trying so hard for something that she could care less about fighting for back. I deleted her number, deleted all our messages, and unadded her from everything. I loved her more than anything and I tried so hard to make things work but she left and now I have to accept it's over but it's so hard, how could she be so okay with losing me and becoming nothing more than memories? I never thought it would end this way.
