I was thinking about how your SO said, that figures when he asked if you heard whatever on his radio show.
I was thinking about his complaints in the past, you not calling him during the day, not showing interest in him etc.
I was thinking about how you realized that you were always a bit more attached and he was always the clingy one.
It gets very tiresome to be the one always pursuiting and very invalidating as well. Whereas a young OW would feed his ego and chase after him.
I think SO really loves you. I know that you want to deal with the relationship problems that existed before his insanity hit.
I think you're doing an awesome job at detaching. I think you're donig an awesome job of keeping your mouth shut. I think you're doing fantastic not answering the phone all the time.
Now, to tip the scales...I don't recommend pursuiting him at all. I do recommend listening to his radio show.
Next time you have a normal conversation you can just ask him a question about soemthing he said, or perhaps tell him you laughed when he mentioned whatever.
Don't pursuit him, but when he comes to you, reward him by letting him know that your interested in him, in an unemotional unclingy way.
Since your SO's a DJ--- what inspired this post was the Grateful Dead song, High time. It's the second track on Workingman's Dead.
