You are in a tough spot of being torn apart by two people that you love.
I reread your prior post when you discussed a lot of your problems with your daughter and your husband before she went to stay with her dad. It sounded like your house was in a lot of turmoil then and that there were a lot of damaged relationships between everyone in the house. You said you left a little guilty about her going, which is probably why you are so happy to be having another chance to have a relationship with her at home.
After she left I bet the mood in your home and the stress level were much improved and that made things much more pleasant for your husband and your younger child. That may be why he is so upset that she is back. He probably has too many memories of confrontations with your older child, problems with the way you dealt with her and the impact of what this all did to your family.
These problems are not going to get fixed overnight. It sounds like your daughter may have grown up a little, but your family really needs some counseling. And probably some space. Did your daughter finish high school? Maybe an apartment or a dorm close by would be a good solution. You all could continue counseling until there were some bridges repaired. And you could continue to see her on a a regular basis and help her continue to develop into a mature young lady.
Your husband needs to grow up a little. And attend the counseling sessions, too! If you all want any chance of getting this family back together, you all need to be working together. Find a good church that can give you some structure and teach you (everyone) to pray for your family.
I guess I remember Ann Lander's advice: Are you better off with him or without him? You saw what raising a daughter without a dad did to your first child...what are you creating for your second child??
Good luck!
