You would be surprised--- My childhood friend did the same thing to a guy she loved about 8-9 years ago. She was the love of his life. She messed that relationship up. He didn't give her the time of day for 5 years- until 2014, when I called him up and just asked him to talk to her (He and I met later and became good friends, then I found out they knew each other/dated). He told me that he planned on speaking to her anyway- and me calling him just affirmed his choice. They spoke, caught up, she owned her bad behavior and they started seeing each other again. Earlier this year, they got engaged and she moved to his state to be with him.
If you get the chance to speak to him- own up to what you did and say you were scared- then see what he does and be receptive to his actions. Marriage minded men have a hard time finding the right woman for them as well so if he stays single long enough- I would think there is a chance, just like what happened to my friend.
