Welcome to the forum I thought I would never need my self. You will get good advice from the supporters here.
No, you're not a sucker - not because of this at least. You are probably just dependend of your wife.
There can be no working on your relationship as long as her affair hasn't been ended. You need to be ready to loose her in order to save your self and maybe have a chance to win her back, because you have lost her at the moment. She is deep in her affair fog and can't think clearly.
You will need to do the 180 on her (links will flow I am sure). You have started off well by separating - only it should have been her, that moved out, since it is she that wants to live a singlelife.
Take care of your self. Work on your self, eat, sleep, work out and connect with your own self - this is very important. So good that your have seeked IC at this point.
