Ian, I think if you need to leave, then Godspeed, I wish you well.
Lots of my friends who used to post (IamTJ, Daisy StrongOne) they all stopped posting when they didn't need the board anymore.
Not sure if a grand proclamation or farewell is necessary though because I have also seen lots of people say goodbye and then come back because they really still need the board. But, if you truly don't need it anymore, than more power to you!
Those of us on "surviving" are not here to save our marriage. Our marriages are over and we are moving forward with our lives. Part of that moving on thing is about socializing. Some people don't have too many people to socialize with in their hometowns, or the people they know don't understands what they've been through and so they get some of that interaction they need here.
Even though we are recovering from heartbreak and mostly okay with how things are now, sometimes we hit a low point and we need help. I am more than 2 years out from this nonsense and I still get into funks that I need help pulling out of. And where do I come at 1 am when all my friends are asleep and I'm feeling so sad and lonely? I come here to vent or moan or troubleshoot.
In the in between times, when I am feeling fine and dandy (which thankfully is most of the time), I come here less often and when I do visit the boards, I come here to be light hearted and support others and joke around. Sure sometimes it's just down right silly, but I like to keep this connection because it has meant a lot to me and the people are true friends. I feel very sure about why I need the boards and why I still come here. I see nothing wrong with it being a social venue in this particular forum.
Perhaps you will reconsider, perhaps you will fade away, whatever you decide I hope you are happy and well and take good care.
