I am probably more hard-core when it comes to this topic, but I personally don't see how dating helps your cause if you are trying to save your M and family, which is why we all came here for initially.
Yet, if you know you are done standing for your M, then go for it - file for D and start dating.
It is worth asking - Many times we blast the WAS who has an OP and label him/her as a cheating spouse, yet how is it different if we go do it as a LBS? Do we have permission / validation just because we are sad and lonely? Wouldn't that be a double standard?
