It just tells you EVERYTHING, doesn't it? It's like, "Here's your own personal Marriage Mirror! Have a look!" You can't unsee a prick, can you? He's shown you exactly who he is and how much he thinks you're worth.
I'll never forget my mother explaining to me that our neighbour, lovely Mr. Silverman, was divorcing his wife of 30 years a few months after his bypass surgery because in sickness he'd learned who his wife really was: Unloving, uncaring. That stayed with me. Who they are in your sickness is who they are to the core. And I'd be following Mr. Silverman's lead on this one, OP.
I was in hospital. My artery tore while out on a walk. It caused a full blockage and I had a heart attack and collapsed on the street. Someone called an ambulance. I was blue lighted to A&E and met by the crash team as I went into cardiac arrest. Big stuff. Life changing. All of that. 6 months recovery. Anyway, my first night in cardiac ICU, my husband stayed home. Didn't come to see me. When he finally did, he came up to me and said, "I realise that I do love you after all." I was so sick and so unwell and so weak. But I remember putting a pin in that and thinking, "I'm not going to let that comment slide. When I get to the other side of this, I'll revisit it."
Four years later (and for many reasons, but the main one being that he is an absolute luxury size cunt) I am emancipated from that asshole.
I wish you, with all my heart, the same freedom, in time, and when you're ready, OP.
