Update: I have returned home, after staying at his mom’s for an additional night… it was over 24 hours before he wondered where I was, and not until yesterday early morning that he was more himself and wanted me to come home. He was grateful to have me home, has been sober for 2 days, we were even intimate… but he is still very lost mentally. I believe all things are possible, so I not only believe in him, but in his ability to heal from all of this… I do fear that his delusions may create long lasting damage to our relationship from what it was prior to the drug relapse. Unfortunately, psychosis can cause very very real experiences and delusions, both visual and auditory. So he will have some memory of these experiences for some time, and due to all of his past traumas, it is a strong form of delusion to fight with. I feel I can only prove my love and loyalty with time and actions. It may be a tough road but I’m willing to walk it with him, I love this man dearly, and if there is ANY chance we can get back on track and get back to our dreams, I will fight for it. I think it is going to take alot of work, it may take meds, therapy, supplements, me working from home, possibly moving to an area where drugs are not so readily available, and alot of care, compassion, and trust building. It is a shame that drugs can rob people of so much life… and what’s worse is most of us turn to them because of pain and loneliness and the medical and mental health field failing us as patients and as people. I pray that we can slowly rebuild our life and that his quality of life only improves from this point on. We shall see in the coming weeks.
*Update- After another relapse, we have finally been able to maintain sobriety and my partner has stabilized greatly. It has taken time, patience, and much love, compassion and understanding. We took a short vacation and went camping, and nature seems to be very helpful medicine. He was still fighting cravings alot but that has slowly subsided as well. Unfortunately after discontinuing substances, depression and low energy are fairly common so he is experiencing a bit of that but overall doing well. He does still experience some of the schizophrenic symptoms at times also, primarily delusions or auditory hallucinations..but managing them pretty well. 
He has expressed a desire to be institutionalized if he feels as though a relapse may again be possible, and I feel like this is great growth and progress for him and I am very proud of him for being proactive. I love my partner beyond any words and I am very grateful for where we are in our journey thus far. There is always hope when you have love and faith in each other… even when things seem hopeless at times. I pray that anyone else fighting these battles can see the lighter days too…
