He is "officially" yours, Tim. In your heart and soul, S13 is yours. Keep talking to him about the counseling. Share your experiences and hopefully it will help him see that it would be beneficial. So sorry that your and S13 are hurting so much. This is probably the hardest part of the whole process - watching your kids hurt so much when another person selfishly walks away without trying.
