Listen to your gut. I've been there, done that, and it isn't a nice place to be. I'll include a link for you to a support group I started online for sex addicts and spouses of sex addicts. You don't need to join to look around, but you would be more than welcome. You can go in and read the stories and the links, books, anything that is there. If you want to read my story, it's in the Our Stories section under Angel's story.
If you would like, you can feel free to email me as well. Just be careful. I hope you find the answers you are looking for. Take care.
