After visiting with him this weekend, I left a note on my way out. It was sort of like the closure I needed. It briefly stated how our relationship was full of unhappiness and I tried to change him. Needless to say, I DID undermine him at times and I did try to stop him from doing what he wanted, but he still did it anyway. This was not OK on my behalf and I made sure to mention it.
On the drive home this morning (3 hours), I turned the music up all the way (I'll be lucky to not go deaf), and rocked out down the interstate. I am feeling OK. Haven't eaten yet, but I am going to here in a bit. As for him, I'm hoping he will continue to stay background noise.
