I'm gonna buck the tide here a little. Let me say this and then I'll be interested in everyone's thoughts:
I don't think we've "gotten over" being a witness or being duped or mislead or whatever you wanna call it as long as we continue to show up here and post on a regular basis. I'll go away for weeks at a time and think I'm done, I've gotten it out of my system. I can go on with my new life. But something will happen that brings back some of the feelings that I had when trying to come to grips with the whole deception thing. When that happens, I come back here and become a semi-regular again, posting on subjects that interest me.
I know that I have been here a very short time compared to many others and I don't want to offend anyone, but I feel that this is a great place to learn and to use to help yourself heal, but at some point, to completely heal, you have to leave not only what hurt you, but the place that helped you get over it. It's like getting hurt and going to the hospital. At some point, you are healed and you must leave.
I'm now open to entertaining differing opinions. I'm not trying to start a flame war, I'm being truly honest in my thoughts here.
