There are soooo many nice people here on the Dis, but there is that handful that never have anything nice to say, and are always playing devil's advocate. Sometimes I think people would be better off not sharing some of their problems here, because I think that the negativity of some on the board could do more worse than good. The anonymity of being on the internet and tossing out questions or info just to get advice can be great though. I know there are many here who wouldn't mind a PM to discuss whatever problems have befallen you as of late, and could provide that needed shoulder to hypothetically cry on. I would not suggest sharing any intimate details that might be "fresh wounds" for you in an open forum, b/c as I said many can be harsh, and even if their intention was not to be cruel to you, in a hightened state of emotions you might take it the wrong way and it could further set you back!
I know that it wouldn't be an immediate help, but perhaps you could join a book/sewing/aerobics club (insert any club) and meet more people. I don't have any room to talk as I am not a "joiner" by nature, but it could be an affective way of meeting new friends (with similar interests) who wouldn't be attached to your husband.
