The attorney I consulted is by no means a shyster and would actually like to see us stay together.
As to the original question about when to consult, in my case it was seeing emails and photos of her with OM on top of phone records with another OM. This is not what I want to do, but her behavior really leaves me no choice.
Do you have evidence? Has she asked for the D and/or moved out?
