"but can you say why you want Luke to work on his r with his w so much?"
Sure. For a number of reasons.
First of all, I'm not saying that he should have a relationship with his W to save the marriage. That is not the intention here. With that being said, I think he could try having "some" kind of relationship with her.
1) She will always be the mother of his kids. If they break up and there is no positive communication between the two of them, it's going to be hard on the kids. Especially with his daughter. Later when she or his son gets married and wants to introduce their spouses to the family, it would help if there was no tension. You don't want the kids to choose sides.
2) They are still living together under the same roof. Why not try to improve relations between them? I mean he has nothing to lose.
3) To help LL with his personal growth. Right now he has hit an impasse and not moving forward with standing up for himself. He seems to always come to a certain point in his growth (with his W which I feel will spill over into his relationships to women in general) and then stop. He can keep moving forward. Right now it seems like he's just avoiding her out of fear. Time to get rid of that fear.
4) Based on his post just before this one, it's obvious he's feeling lonely. We all would. Why not try and communicate positively with the woman he's living with? GAL is fine and great, but he's been living together alone for so long that he needs/wants/yearns for a connection.
The good part of all this is that he's actually beginning to FEEL lonely rather than accepting things as they stand. Luke, you can do something about it learn how to truly DB. Do what works, don't do what doesn't, and don't give up on yourself.
