Hi, I only think you should file if you are truly ready to end the marriage yourself. Don't file because you hope it will 'wake her up' or have some effect on her. Do it only because it is the right path for you. You will need to live with and be at peace with that decision. You don't sound ready at this point?
So, she isn't going to leave the house by choice? There are other options. You may choose not to share the MBR for example and move her stuff into another room - letting her know that you aren't willing to share the MBR with her if she is choosing not to be in this relationship.
You may also choose to move out yourself. People tend to advise against this on the forum and sometimes there may be legal considerations to that option. I left the marital home at BD and (in a way) I never regretted that decision - though it left me in a financially precarious situation for a good while.
I think the key question is - given that she is doing what she is doing - what do you want/need to do to look after yourself and your own interests?
