Re: Used and Abused.
I know that this is the probably the toughest thing to do and also the easiest thing to say coming from someone like me who has no investment in the situation. But seriously, walk away, move on and don't look back. One of the best things you can do for yourself is to make these difficult decisions and do it with grace and tact.
Trust me, you'll be much better off writing this person off at least for the moment. On top of that you don't want to burn any bridges with anyone else in the group. You never know when someone that you've worked with in the past perhaps affiliated with this situation with think of you for a future project.
