Friends or more?

I hope someone here could help me. I went on a date with a guy..well, it was a date as he said let’s meet up however neither of us used the word “date”. I have a bit of crush on this guy and we used to text a lot – from that I also started to like him as a person and really interested in getting to know him better. I really thought he was interested as he did ask to go out for dinner in the evening while walking me home from our date. But as I had been so stressed with nerves already and felt like I wanted to take things a bit slow plus also not hungry at all due to all the nerves I said something like no thank you as I am not hungry…His offer to have dinner seemed to me as he was interested. Anyway, when it was time to separate it was kind of abrupt/rushed as I just said a quick bye and nearly ran away from him. I am a very shy person and anything like kissing on the first date is a bit too much for me – hence why I ran away. I did text him though same eve to tell him thanks for the great time and that it was good to meet up with him ect to which he didn’t really comment. He didn’t write to me after that at all… He then told both my friend and to myself that he did like talking to me and would like to meet me again in the future but only as a friend. He asked several times if I was interested in meeting him as a friend. I am of course happy to remain in touch with him but have to admit why he wasn’t interested in any more dates by clearly telling he only wants to be friends. I am really confused as he did come across really interested, especially offering the dinner at the end of our date while walking home..He comes across like a very shy guy too e.g. he is chatty in the text messages but whenever we speak on the phone he goes very quiet. I will be the one asking questions to keep the conversation going. Also during the date, he did talk but he seemed shy/nervous. There was lot of eye contact from his side. To be honest, it was me who was too shy to maintain the eye-contact and kept looking away. I have a feeling that he also likes me and wants more but that we both were so nervous and shy and perhaps gave each other the impression that we were not interested in a 2nd date? Any idea on how I could fix this?? I obviously don't want to chase the poor guy and just trying to remain a good friend but truth is I do see him more than a friend! Please advice/help. Thanks in advance
