My Wife is Having an Affair with Co-Worker

[LSG]

Communication is little to nothing between me and my STBXW. We argue if we do talk. I am wondering what more I am able to do to be effective in a last ditch effort to save my M if possible.

She seems to be totally against working on the M and continuing her A with OM.

I know everyone here has good ideas to help me to do my best to deal with my situation.

Please give me some advice on how to proceed from here since my W has already filed for D.

Thank you!
