Is what I said ok? What do I do next?

This guy I met about a month ago through one of my friends liked me and we’ve been talking basically everyday and going out almost once each week. Since the day we met and exchanged phone numbers he has been calling me or msging me first almost everyday. A few times it was oppossite. Not because I’m not interested in getting to know him, but because he works until late and doesn’t always get off work at the same time so I thought I won’t bother him I’ll just wait. However, as for being interested, he does seem interested but not at all enthusiastic. Why? Is that just his character? Furthermore, the other night when we were at a club I was talking to another guy for a few minutes towards the end before we were going to leave and when I turned around he had left. I found out afterwards he had gotten jealous so he took off without saying goodnight and asked me through a phone msg to start going out, become boyfriend and girlfriend. I replied I have to think about it and we’ll talk soon. Yesterday and a while ago he asked if I thought about it and what my answer is and I told him although I’d like to get to know him better because I like him let’s try and see how it goes. How does that sound? Is what I said ok? I don’t want to rush into anything because my last relationship which was also my first didn’t last for very long because I didn’t know the guy too well and rushed into saying yes and ended up not liking the guy that much which was unfair too him and wrong. What do I do next?
