Question about MLC and MLC'ers desire to help

[2ndnoah]

I am thrilled your hubby moved home. Mine has been gone 3+ months. Tough day today.....hubby said he is never coming home. No progress made during this time. I have begged, reasoned, logic, explained, promised, etc. Didn't work. Doesn't work. Maybe I should try the tough love way. I have been the nicest, sweetest spouse during all this. Not a harsh word spoken. He is MLC (textbook) and has a girlfriend but denies it and will go to his grave before admitting it. He walked out 3+ months ago and has never turned back. Has not changed, is angry and sad. Wants to yell at me when he sees me which he only sees me maybe 1X a month. Just lately, a couple of times he has confronted our S19 as to why he will not talk to him and have nothing to do with him. S19 told him he has nothing to say to him, and that he is the one that left. S15 is getting the same attitude towards H. Sad! Should I file for D? and do this tough love thing??? he continues to deposit his check. I pay the bills, etc. only thing that has changed is he is not around. My boys were very close to him. We were a "beaver cleaver" family. Greatly involved in our boys lives, community, etc. He now is gone. I miss him and am so crushed as well as my boys.
