You have absolutly no finacial obligation to pay for his rehab. I am in the same boat. In the midst of seperation to my husband-addicted to crack
We have 2 beautiful children. And now for the first time in 12yrs I am taking care of me and my children. i will not and cannot invest another penny or sleepless night into him. Explain that yes you do care for him, hope for recovery but you cannot pay for this. Your focus is on your children and yourself. Believe me I pray my husband gets clean, for the sake of his children. But I tell you it will be on his time and dime not mine!!!!
Sorry, it just sounds like were in the same spot right now. I have given that man 12yrs of my life and looking back the majority of them were hell on earth. When I think of the things I and my children have been through it makes it easier to say NO!!
Take Care you you and your children!
