I thought so, at first...
I came off the site for a number of years as I went through a bad patch with my mental health. My ex would blame the site for my behaviour change, and I came off also to keep the peace. I also thought that the site was full of negative folk with the LTB attitude just for the sake of it....
Coming out the other side of that time, things would pop into my mind of things I had read, and I was living that life. I was in a poor state mentally because of how I was being treated, but I swept that under the carpet along with everything else.
Some years later when more had sunk in, I came back and got a lot off my chest, I didn't always agree with the replies that were being posted, and a lot of the time I didn't want to hear what was being said.
I did end the marriage, and now I am in a much better place.
This is why some of the comments of people wanting a blow by blow account of someone leaving really irritates me. I am one of those that took years to be able to make that change.
So to answer your question, yes I thought it negatively impacted me when it was easier to not see the truth.
