I know for me it's that I try to always see the best in every situation... no matter what. So I always forgive people no matter what (if I have stong feelings about them). I haven't been able to let go of someone for 7 years now and we aren't even together... but I can't let go of it. It feels like it's something inside of me that won't let me. Also, I always think if I do let go... what if something could have happened had I not. I look at things like it would suck way worse regretting something that you didn't do as opposed to something you did do. So I'd rather just keep on and see what happens than to let go and never know.
