My partner is a member here. I think it's affected his behavior in that he doesn't post anything that would make trouble for the mods because then he'd have to put the kids to bed while I spent the evening locking down threads.
That is a joke.... actually I don't read his posts. He is welcome to read mine but I'm not sure how many of them he's read. We've talked about a few of his and a few of mine.
In "real life" I like to bounce ideas off of people and he tends to gather some information and then keep his thoughts to himself until he's made up his mind-- and that is pretty much how we each use these forums.
I found the site first, when looking for information about male SA after he'd disclosed. I asked him if, in all his time acting out online, when the SA was clearly on his mind in some form, it had ever occured to him to look for information or support. He thought this was very funny. (Now that I know a bit more about acting out, I think it is kind of funny too.)
At first he was upset that I came here, because he felt that I was trying to affect him or his healing. It was difficult for him to accept that I needed support and healing for the way that his abuse had affected ME-- that I wasn't here to try to change him, or try to manage his healing, or try to "figure him out" (like that's going to happen...).
He told me later on that part of his difficulty about this, was that he wanted to deny that I needed support or healing because he didn't want to face up to the ways that his SA had affected us, and me.
