The DW's son is going through this now. Found out the son's wife has been making him sleep in his oldest sons bunk bed because of "snoring." Bitch, go buy some earplugs or take your ass to the couch! Now, for the second time in the last 4 yrs. has threatened divorce. Initiated papers against him. Something regarding "bed and board" which is N.C. law that has six criterian to meet that are so vague in nature it shouldn't even be allowed into a court. I have my own issues with this male dominating (2 sons and a husband), liberal school teacher fairy princess. After talking with each other DW and I have counseled to just end it. Use whatever he needs from his 401k to hire a bulldog lawyer. All that matters is equal custody.
Personally I advised a P.I. If she's banished him from the bed for 2 yrs. she is getting something on the side. Guar-an-tee.
