What DQ said.

Own your own fate. You already know what it is to let your W control your fate. She cast you aside and left you behind, and you are sitting there waiting for her to come back and pick you back up again. Do not wait. Do not put yourself on a shelf. Please love yourself more than that.

She already cheated, and we can be pretty sure she still is. Would seeing the light on in her apartment be that much more horrifying than what she's already done to finally make you stop waiting for her? Please don't spy for THAT reason. Just get the ID on the guy and leave without confrontation.

Start creating a life that you will love living. Start to envision what you want, with the assumption that she is gone. Stop waiting.

CAPISCE???
