I remember reading that a separation is less likely to end in D if mutual friends are pro-marriage. This was the closest I could find on the topic, but the research it refers to just talks about how "social contagion" can cause a mini epidemic of D.
Ugh. My H's friends and family are more like, "Do whatever you feel you need to do to be happy. If that means getting a D, then we'll still love and support you no matter what."
I have such a (mis-guided) urge to share DR with my MIL or some of his friends, in the hopes that they will be moved to encourage him to reconsider.
That would be SUCH a bad call on my part, so I'm thankful I've resisted those urges so far... but boy oh boy, I think this would be easier if I had more people in my corner. (I mean, I know I have all of you, but I mean people who actually TALK to my H!!)
Had a very positive interaction with H when he brought D home. He said the house smelled great, and noticed all the (clean) pots and pans I had used: "Looks like you've done some cooking!" with a smile.
Then, when he went to say goodbye to D, she put her head down, made a sad face, and shut her bedroom door in his face.
