Thanks Codejob. Yes I saw the photos from Facebook.
I feel like I've been addicted to the addict and it's no longer feelings that keep me trapped but an unhealthy obsession and focus on someone else's business. I should be happy that I discovered the lies and I should just move on. Yes she was an addict too. I bet his relationship with her probably never had a clean end either. I now remember a lot of red flag, all indicating that's how he handles conflicts in relationships.
My selfish and not so loving thought is that he really put himself together this time and they are back together in love while I was the one that meant nothing to him perhaps just someone who got him into rehab. I know this thought is very unloving and selfish. You are right I am old enough to mind my own business and work through my issues to find my happiness. His life really has nothing to do with me now. And it has always been his life and his choices. But I can have my life and my choices. It doesn't not need to revolve around him anymore.
Thank you for your post.
