He sounds uncannily like someone I once considered the "love of my life" 🥰🥰🥰 It was easy to romanticize him because he was so charismatic and wild. A beautiful Heathcliff, or so I told myself. For years!
He was also incapable of doing anything other than weave a path of destruction through the lives of anyone around him. Any efforts to help him backfired spectacularly: he'd borrow money he had no intention of returning, break things you lent him, and still insinuate that you should be giving him more. He never made any reparations. He didn't give a shit.
When I finally decided to prioritise my own survival, the only way I could do it was to move house and cut all contact, because he was the sort of person to just turn up on the doorstep in crisis (van has broken down, kicked out of flat, lost job, etc) and expect to be looked after. Indefinitely.
Yet even after leaving him, my heart continued to bleed for him.
It did wear off though, over time. Now that I am happily married to a truly kind and loving man, I look back and wonder how I put up with it for 10 minutes, let alone almost as many years.
People like this leverage everything they can to manipulate others - suicide, illness, whatever: they live on the brink, demanding rescue. But surprise, surprise: 20 years on, he is still going strong. I saw a picture of him on FB recently. The looks have faded, and he now looks every bit as corrupt and depraved as he always was.
Good luck OP, you're on it! You'll be fine!
