Yeah, that is a long, hurtful relationship. I had an ex who would fight with me all the time. We would break up, get back together, break up, get back together. She would also put me down a lot. It took me a while to recover from that. Ultimately, I ended the relationship and I just forgot about her. I treated her like she no longer existed. I think you did the right thing and I would just forget about him. Sounds like scum to me. The thing about garbage is that you just have to throw it away and that's what you did. So, don't care about him so much anymore. Forget about him, and move on. You made a mistake and you will learn from it. Best of luck in the future!
I will do my best to reply with an educated, humble and honest answer. Ultimately, it is up to you whether you want to listen to my advice or ignore it completely. Sometimes, my advice may be wrong; occasionally, it will be right. Regardless, I want to do my best to give people answers they are seeking.
