Happy Thanksgiving to me:(

This past week the day before Thanksgiving I found out that my husband has been having a affair for the past three months. Not just a one night thing a passionate relationship. I had my suspicions but no evidence until (bad me) had my 16 year old son crack my husbands e-mail account to find videos of them together. Having these images in my mind makes it to real. The pain of seeing it cuts into my heart. This was and is the most devastating thing I have ever gone threw. It is so funny how I always said that his butt would be out the door with no questions asked....Well now that this has happened my feelings have now changed. I want to attempt to make this work. I know I love him but can we make it threw this. Of course he has been a mess trying to deal with what he's done. He says it was a mistake he wishes he could erase and that he will do anything to make everything ok again.
Sometimes I think this situation is driving me  mad. The girl was also 8 years younger than me and not bad looking. I can't say how damaging this has been to how I look at myself. I have never felt so ugly.
Thanks for listening:)
