Awest...that is a choice only you can make. Let me just offer some words of wisdom: if you are done, then you are done. Make sure, be sure, and use the 48 hour rule...don't say or do anything for 48 hours. If at the end of that time you are still unsure, then continue it.
For many, there does come a point in time when we have just had enough. This roller coaster is exhausting, and although some brave souls have chosen to stay on it, some others have just decided that life is too short and they decide that in the end, they have done all they can. Make sure that within yourself you are satisfied that you have done all you can before you take the next step. If you don't, you may end up regretting it.
Im still standin better than I ever did looking like a true survivor feeling like a little kid Im still standin after all this time and Im picking up the pieces of my life without you on my mind..
