Lost a good guy due to unresolved past

I was meeting this guy for arranged marriage. Spoke to him over phone for almost a month..and met him in person 5-6 times in person. He is from a good family..and both families were happy with alliance. He was all for it.I was still making up my mind but liked talking and meeting him.He had only one condition, if I had any ongoing affair with another person. He suffered bad heartache last time around, when the gurl he was engaged to, was very frequently calling her ex-boyfriend, and was not able to forget him. He broke off the engagement with her. I told him nothing going on. Towards the end, I was also getting close to him, and one day he asked me same question again, if I had any heartbreak. I admitted, as I was in an on-off, complicated relationship with another guy for nearly 7 years, but was serious about this marriage thing. He asked me if I am still in touch with him..and for some reason I just couldn't lie to him, and told him yes..talk to this old guy once in a while..sharing updates of my life. This ticked him off..and he called it off between us..though I tried to explain and reason that I really like him. He said he does not doubt my honesty and is sure if we got together I would completely forget the other guy and be happy with him. But he said due to his past experience he does not want to get involved in such a situation again. He advised me to stop all contact with previous guy and break up completely before trying to get married. I know he is saying the right thing..but I really started liking this guy, and feel bad about loosing him because of my unresolved past, which is not going anywhere. He did tell me..he respects me for honesty and likes me as a person, but cant risk being involved in a sticky situation. Please advise...I respect his decision, but feel bad on losing him out..He really was a nice genuine person. I wish I could convince him, that I am all for making ammends..and my intention was never to cheat him. As I started getting closer to him, he started taking the priority in my life. Please provide some wisdom to an idiot that I am and made of myself

I believe this problem is as simple as you already know it is. The guy you've been talking to for 7 years off and on needs to be shut out of your life completely. You need to get over this man as if he moved to another planet and you'll never ever see him again. The reason this other man said he doesn't doubt your honesty but he can't risk being in another sticky situation is because the last time it happened to him the woman made the exact same promises you are and it doesn't do anyone any good to accuse someone of being a liar. For now I think you need to spend some time single. Allow yourself to feel the pain of being single and learn not to depend on others for your happiness. You can find a peace within yourself that way and once you do then you should try to find someone. He's right about that. The universe rewards self sacrifice and for now I think that's what you need to focus on. I know this probably isn't what you wanted to hear but jumping from one relationship to another will be messy even if you're doing it with the best intentions.
