I was seeing this girl got pretty serious however on some occasions she was rude and showed loads of disrespect.

I told her I’m not going to talk to her till I decided whether I want to see her again and she can do the same thing.

I haven’t spoken to her and I can’t really be arsed. She sent me this message yesterday:

Il take your lack of contact as an end to any relationship we have had. A bit disappointed you have made no effort to even let me know what you decided, even after asking you to let me know. Closure was all I wanted, clearly you don’t value our relationship as much as you once suggested. X

What would be a good/chad response to this?

Thanks
