Husband is lost and in pain

My husband of 27 yrs is lost. He says he doesn’t know who he is, doesn’t like himself, and has put others before him his whole life & he’s done – that it’s all about him now. He’s chasing the flesh of strippers half his age, has alienated his 17 yr old daughter who now says she will completely cut him out of her life once she moves out, and wants a divorce. He is struggling – fighting back tears in his frustration when trying to convince us it’s all our fault this has happened to him. He needs help only God can provide. We love him, and can’t help him. It’s a very helpless, hopeless feeling. I pray God meets him where he is, because he is so far into this pit he can’t see the light any more. I pray God will show him mercy and love and pull him out of this, reveal to him his purpose and set him on the path He has laid out for him. I pray He will restore his relationship with his children. And I pray he finds peace and happiness. And I pray God will stay with myself and my daughter and help guide us through this storm. Please help us.
