I stumbled on the Loveshack forums around 2011, and the info from others' life experience and advice there helped me to relearn relationship behavior and analyzation, leading me through a lot of difficult personal self-examination and eventually to a very healthy relationship:)
Of the several relationship forums I read and contributed to, this one was the most active and wide-ranging. I didn't agree with everyone's thoughts, but the majority of posters were obviously contemplative adults, which I really appreciated.
It was of course a narrow view into human psychology, but a valuable one for me. It was so much more interesting and productive to spend minutes or hours there during a week than Facebook, and I now I miss it as part of my life.
Features I especially liked were the 'like' button for each post which provided encouraging feedback and a reference if you weren't sure advice was worthwhile that others did or didn't think it was worthwhile, the easily navigable main menu, and the many separate topic boards. There were rarely any spam messages left up more than a few minutes - only real questions and real replies, and a few lonely or trollish posters (who are still real people, not advertising bots). It was quite rare to go a day without a thread being replied to many times - and typically several new threads were begun each day. A very active board :)
