Seriously confused

I'm in a seriously confusing issue. I dated a guy that I worked with when I was 16 and we dated for almost a year. He was 22 at that time and although it is a huge age difference it never bothered either of us. We got serious and fell in love. We had a great relationship. Only problem it was a secret. My parents found out and made me break up with him. I hadn't talked to him in more than 8 months and now, being 18, he reached out to me. We've been talking for a month now and have only seen each other once...and we hooked up :/ I want a relationship and every time I bring it up he doesn't answer me or he just gets so cold. What can I do? I know he cares about me. I can see it in his eyes. Some help would be great!
