Worried but what can I do

Well, found out last night from Sean that Spanky more than likely didn't go to work last night.  He said that he saw Spank's jeep outside EMA.  What would he be doing there?  They didn't need search and rescue.  Maybe he took her in there to meet people, who knows.  Also found out that he is taking Adapex to try to lose weight.  He is gaining WAY TOO MUCH water weight from it and i'm afraid of what it will do to his heart.  You can't drink or smoke taking that stuff.  It WILL kill you.  I cried so hard after finding out.  What is he doing to himself?  Yes, he can stand to lose some weight and get rid of the sleep apnea, but THIS is not the answer!!!!!  OMG- I love him too much to see him destroy himself but what can I do? He is with Rayna and I know she has no clue how to take care of him. 3weeks to 3 months- I keep telling myself that it will be over with her and he will have hit rock bottom by Labor Day. I hope that it is true.  I want him away from her so very badly before she kills him.  If I lost Spanky, i'll never forgive myself for letting him get away.  I'll always wonder what I could have done to change things and what I could have done to save his life.  I love him but had to let him go in order to get him back for the long haul.  We ARE meant to be. He knows that but can't admit to it.  God- give me the strength to get thru all of this.  To love Ronnie from afar, to pray for his safety, to hope that we can be together once again.  Keep him safe for me and let him eventually see the light of what he is doing.  He's my baby and I love him so very much! Thank you!
