I overthink my relationship with this person in my head a thousand times, pointing out all their flaws, thinking about the things I could do to potentially ruin their life (although I would never act on those impulses really.) Then, when this person gets fed up with me being rude to them and viewing them in the worst light and they try to leave, I beg for them to stay and I start to think about all the good characteristics they have. I start to cry at the thought of them leaving me. I hate how I can go from wanting to cut a person out of my life to begging them to stay with me.
