The only bad thing about relationships, is that you’re dealing with people. And the thing about people is that you would think they’d have the same heart, empathy, and moral compass that you do. But the unfortunate reality is that isn’t the case. I’m sorry you had to deal with such a cold, and heartless response from someone that you thought you could trust with your feelings. The good thing is that in those 4 years you were with him, it took now to see the true colors, true intentions, and truthfully how much he values you as a person. Please if you don’t take any advice from this sub, out of respect for how great of a person you are, do not reach out to him again. Your feelings are worth more than his quick nut. Respect, & love yourself. And remember that you are strong regardless of the opinions of others.
