Pity party. I actually feel pretty offended that you come here with this cr@p. After all the stuff that is dumped on us by our relevant spouses and all the pain, lies, hurt, realisation and acceptance we have to go through, you want to give up before you've even begun.
Get a grip of yourself, grow a pair and get help. Stop the woe is me act - we are the wrong audience for that as ww see it every day.
