Your post is relatable to me. A few years ago, I separated from my qualifier, and he moved far away. I'm still in love with him.
I was shocked to receive a message from a person who identified herself as his "new girlfriend ". She asked me to talk him into treatment because she said he might listen to me.
Oh, if it were that easy! All I did was wish her luck.
I'm still in contact with him, and I know he has no intention to seek treatment now or maybe ever. It doesn't affect me in the least, though I do still care about him.
I live my life, but I have not been interested in a romantic relationship with anyone.
I hope you continue on your path to peace!!
I wish you well!!
