It seems to me that the best way to get over my heartbreak is to just keep focussing on myself and whenever she pops into my head I should immediately question why I'm thinking of her and focus on my feelings at that moment. I'm managing to ghost her texts. Next step is to tell her that "No, I don't want to go for a walk and chat" and that if she has a specific question, she should email it to me.

It's hard to put into practice, being that I feel so heartbroken over her/us. But, this torture has to end sometime.
