SB - when my H initially read my thread, he was worried about the same things. I think he quickly saw how innocent it was. His nose was a little out of joint at first, because he thought people made light of the pain the WAS's were in. I printed off some pertinent part of my thread to show him how understanding and empathetic people were of their Ses.
H then mellowed out and has promised to stay off the board and give me my privacy (although he did snoop once since). He understands what a big support it has been, and frankly was a little jealous that he didn't have a similar support group.
I think you overreacted, SB. He was projecting onto you what HE did (kinda like my H checking my cell phone numbers last week - AS IF!!). And he loves you and feels pretty worthless and is at that point where he wouldn't blame you if you had an affair, and is fearful of losing you. Don't be afraid of the truth. There is nothing on your thread but a woman struggling to save her marriage and sharing a little black humor with those of us in the same boat.
