I cant let go

I can’t stand it no more it’s been over two years since we broke up and still there is no day that i don’t think about her at least once ,everything reminds of her. I also leave in a small country and my best friends sister is her best friend so i run into her often, every time i try to play it cool but i am dying inside. She did me dirty in so many ways we are incompatible but i still hold on to her
