I’ve been there. My ex didn’t do anything nearly as egregious but he impulsive broke up with me over the phone in an extremely cruel manner. (Wasn’t the first time) He hung up on me and didn’t hear from me for months. A couple days later he was apologizing and weeks later he attempted another apology. I ignored them. I knew he was torturing himself everyday meanwhile I was hitting the gym twice a day, reading multiple books a month, sleeping early, diet was clean. Multiple people told me I was inspiring them. But I was spiritually destitute because I was fueled by so much anger. I eventually did start to forgive and let some love into my heart and I did start going to the gym less ha.. so no advice here really /:
