I think taking a break from a forum or Facebook or any internet site is sometimes a good idea. Sometimes it isn't a good fit any more or you just need time away.
An observation I have made - if people post that they are taking a break, so others know they are OK, just choosing not to come for a while, and they post to say so without any put downs about the site or other posters - this is usually met with positive response.
If they say they are leaving and/or make snide remarks on the way out, they get a different response.
