i met this guy online nearly 9 months ago, we have been dating and he was the one doing all the chasing, I was not quite interested then but liked him because he is so respectful kind, considerate very romantic, he invited to his place several times but i found excuses not to go, we finally had sex which was so passionate i started having feeling for him, he end up telling i was so emotional that relationship dont usually work and that girls have really treated him bad in the past...

So he's either going to be insecure and lacking confidence or wanting to get revenge on women. The fact that you acted not interested initially is likely to make him think you are another one whose going to mess him about and it's not attractive when women act un-interested.  And first impressions last.  So what he'll do is either get insecure or will string you along and get revenge on you and all women that have messed him about.

but he came when i told he think about and we try that i am not like that we met twice

I didn't really understand that last sentence.

and for no reason he decided to call everything off...

He'd conquered you, got his revenge on women that mess him about, now it's time to move on. You weren't that interested in him initially and first impressions last. Although it would have created this idea in his mind that he wasn't that interested in you either, he would have been attracted by the challenge of convincing you.  Now he's had his sex, it's time for him to move on, so like you weren't interested enough initially, he's not interested in you anymore.

I am now madly in love with him i am the doing the chasing now, he wont pick up his phone

Well, he won't, because as far as he's concerned, you weren't that interested initially and so you turned him off then.  The only thing motivating him to continue was for you to have sex, now that challenge is over, he's left not feeling attracted to you and remembering that you weren't interested in him in the first place.  He's making sure he finishes the relationship rather than you.

and i am so upset that i am planning to find a way to see him again though

I really don't think that is wise.  It's over and any other potential meetings are going to be pointless, a waste of your time and mean you'll be busy dwelling on him rather than finding someone else.

i do not know where he live could you help me on this Sam i am so in love and he know about it cause i told him that to already

The damage is already done, the most he is going to come back to you for, is if he's not getting any sex anywhere else and you are his last resort.  he doesn't want to answer his phone and therefore that says it all, he really doesn't want to speak to you and certainly doesn't want to get back in a serious relationship.  It's time to move on and find yourself a decent man.  It wasn't the fact that you refused to go to his place that blew things, I think it was the fact you probably acted not that interested in him.  The fact that you didn't go to his place those few times was commendable, because really it was probably too early to have sex and any guy that wants to rush a woman into having sex is not worth bothering about.
