Did i make the right choice?

So a while back this guy added me on facebook, I usually dont accept strangers but he was cute and we had mutual friends. We started chatting online and he seemed like the perfect guy. He was handsome, he had just graduated as an engineer and he was very educated. After a while he asked me for my number and later on he asked me out. We went on a date to the movies and he was a perfect gentleman, he payed for everything. We went on a couple of dates like 5 or 6. He seemed perfect, but i felt like there wasnt much chemistry. He told me I was shy a couple of times, but this was due to the fact that I found it very hard to maintain a conversation with him. This led to me not wanting to talk on the phone with him because if the awkward silences. I eventually distanced myself from him but now I look back and I kind of miss him... Is it normal for me to think I should have tried harder? Or was it normal of me to distance myself?
