Hi @Syfer I am so sorry to hear you are going through this. My husband is diagnosed with a few different mental illnesses to yours but it looks like the partner's experience is very similar for both of us. Except mine has gone down a darker track that I hope you can still avoid and prevent.
My husband is on medication too, and has been regularly seeing a psychologist and psychiatrist but there's been no improvement. In fact, it has gotten worse in the last 6 months where he also has been more deluded than anytime in the past. He recently requested a divorce, and soon afterwards I found out it was because he was having an online affair with someone across the world who he felt sorry for because she can't have kids, and he somehow thinks sharing our kids with her is a way of helping her, not seeing how that takes them away from their real and biological mother who already loves them very much, and also being dismissive of how over the past 5 years since his illness began, I've been beside him through it all. I have two young kids, primary school aged.
ive been the income earner over the last five years too to let him heal but he wasn't appreciative of this. Despite all the major things I've done for him, he could only see my little flaws which he has criticised and nit picked me on. The most hurtful part is that he would rather listen to the voice in his head that tells him I'm the enemy than trust that I've always loved him and always tried to do my best for him. Even though I feel so betrayed I'm the same as you, waiting for my husband to return. I know what his presence feels like, and what he is right now feels like he's inhabited by a monster.
im glad to hear you are getting therapy yourself as it helps clarify and keeps you grounded in reality. Looking back, I wish I had looked after myself sooner. I'm still clinging onto hope that my marriage can still be saved. Each day I pray for the spirit of adultery and lawlessness to leave my household. And I've since discovered there were things I should have done for him beforehand that could have helped him trust me more. We are so busy working that sometimes what they need from us is the emotional connection, but we have to do it their way. Sex and touch are very physical, practical ways of rebuilding a connection. Nice, encouraging words (not my strength, unfortunately) will also help the more fragile and delusional to trust you more. Physical time spent together, talking or watching movies or any other activity together, will also help draw him away from delusion land.
When things feel too tough, don't be scared to bring it to the feet of God, who will take over from you when you're exhausted and reached your tether. All the best, my prayers are with you.
