He was a decent guy, with great personal qualities and a talent for business, as a matter of fact he had a totally legal and successful business (that occasionally functioned as a cover-up, I suppose) but somewhere along the way he got too ambitious and developed an irresponsible taste for an expensive life. Social contact and his friends were very important to him and I think that all his love relationships suffered because of that and his entourage did have have both a good and a bad influence on him. Six months after the break-up I was offered a very good job in Asia, I tried to speak with him again before taking a decision and again I received no answer, so I left. I couldn't adapt very well abroad though, came back two months later and at that time he was in a relationship. I've had very little news of him over the years, I've moved twice since then, until two years ago when I found that newspaper article...The most important thing for me besides learning to avoid certain mistakes I made in that relationship like being too emotional and too possessive at times, was learning to let go and move on. I'm very happy with my life and I wish things would pick up for him too.
If he repeatedly failed at communicating with you whenever you tried, there aren't many chances that this would improve, so it would be wise for you to avoid doing something that only seems to help you momentarily but makes you feel much worse later. I know that you feel that he owes to do you some justice, but he won't - sometimes life is unfair and we have to deal with it. You're the only one who can do yourself justice by accepting it's over, even if it finished in such an unhappy unexpected way and looking for ways to feel better, enjoy yourself and have a happy life.
If he had indeed been the one for you, he would still be by your side. Someone else is meant to make you happier than you've ever been :-)
P.S. Thank you for your kind words, HT. I also enjoy your presence on the forum
