Was I needy? how do I fix this...

So this guy and I have been dating.
He was really chasing me... like he'd text me 10 times a day, and when I didnt answer he's text me again, to ask whats up.
So after a couple more dates, he even flew me out to the country he was working at the moment, and introduced me to his friends and collegues. It was fun!
But than he asked me to show more of my emotions and be more open about my feelings towards him, so I did...
I started persuing him, for example I'd text him, telling him '' I like you'' and ''I miss you'' (and this kind of behaviour is not like me at all, I am usually the one being chased, but I really like this guy)
But than out of the blue he didn't answer to my texts anymore... and calls started to drop from 10 times a week
to one in 2 wks.

So for the past weeks I felt aweful.. I felt as if I was being this needy person I never intended to be.
So I decided to pull back for a while to see what will happends.

But even if he doesn't contact me after a while, how can I start conversation again...?
But without seeming desperate or needy!

I dont want him to think I'm needy at all...
But I dont want our friendship to end either..
What do I do?

I feel like if I contact him too soon, he will find it needy again... so how long do I wait?

First off he expressed to you he wanted you to be more open with your emotions..maybe its an ego thing? Really cannot tell this early on..I would say you do nothing...if he is still interested he will eventually contact you..it could be he has a lot going on at the moment..what sign is he btw?

I definitely think its an ego thing
His bday is Dec 23rd so he's a mix of Sag and Cap.
Does that tell you anything?

I know I shouldn't be the one contacting him anymore, but I just dont wanna lose him as a friend.
I definitely want to stay in touch..
But I dont want too seem too eager either..

If I want to initiate contact, how would I start?
And how long should I wait out till its cool to contact him again?
