I know what you are going through. My brother left my sister-in-law and 3 year old son about 3 weeks ago, he fell out of love with her months ago (so he claims).
They had many problems in their relationship, but since he left she has done many things to correct her problems. She is a MUCH better person since she has sought help, but he is not around to see it.
Problem is, he wants nothing to do with her anymore after 8 years of marriage. He is hung up on some girl he met on the Internet, if you can believe that. He has chatted with her, spoke on phone (daily) and has a picture, but never met her. I hope this Internet "Relationship" with the hot 24-year old bites him in the ass.
Oh well, sorry to rant, good luck with your situation.
Regards,
