I still worry for my ex but not as obsessively, I have to accept that I couldn't help him or save the 'wonderful' part of our relationship, all very hard for a rescuer type. I realise I have to work on that, but it leaves me with a deep sadness.
I can really understand your worry, KAW. I'm sorry that this is happening.
I think those are wise words above. At some point, we have to gently hand back the responsibility of our loved ones' lives back to them. It's hard and often heartbreaking. But it doesn't mean we can't extend that same hand to support them when/if they choose healing. Such a tough balance.
I like the idea of mountain therapy. I also found talk therapy helpful.
Does your partner have a friend/mentor he respects and listens to? Someone you could enlist as a support for him?
Hang in there. We're here for you.
