Total withdrawal- no communication
My 51 year old husband walked out 10 weeks ago, right before Christmas after 24 years of marriage. He has totally withdrawn from me, little to no communication. He has left our church, and seems like a totally different person. He has left all of the responsibilities for our house, bills and my son to me. He never inquires about my son or our other 2 children who are both in college and fails to return basic text messages about our finances or about my teenage son. I strongly believe he is having an affair with one of his workers (he's the boss). I found evidence of such before he walked out. I guess my question is why won't he at least acknowledge the text messages I send regarding my son? He has always been a responsible father. Is this some attempt to punish me? What is the best course at this point? Just to leave him alone?
It is his responsibility to help with the financial obligations of raising your children. If he won't respond to you, I suggest a letter from your lawyer.
If he doesn't respond to that, take him to court.
