I don’t feel like writing a long explanation... I want to have an affair with a colleague!My husband did it for a year and it hurt like hell especially being pregnant and the woman harassed me horribly for a year !! I had No Support nobody to talk to just keep taking the abuse and the pain and everything that went on! Things that he’s now really starting to understand a few years later Because now to him Our relationship is gold! 
I want an exclusive relationship with a colleague..... I want his friendship and his body.... he’s all I think about he’s become my fantasy and I can’t get him out of my head!  I know it’s wrong and I know that I will probably make the right choice not to do anything with this person.... but I’m afraid I will!!! I don’t want to damage my marriage especially since it has improved my husband is really trying but now I am at this crossroads and I don’t know what to do!

In the same boat. I can relate.
husband cheated, once I know, more than once I suspect.

years ago and now he’s all in and all I want is to have my own.
