Met an amazing guy and am afraid of him not liking me

Today I met a guy who I now am head over heels for. We met online 6 years ago and found him super attractive. 2 months ago he got his job transferred to the city I live in, so after 6 years we started talking again, We finally met today and it felt so awesome.We played Pokemon Go together. I really want things to go well, but I am scared of him not talking to me anymore because I have a tendency to be clingy and that has scared guys away. He texted me once after our date. I haven't heard from him in 7 hours and honestly I'm getting worried. I know that he's playing D&D with friends and I've checked up on him a few times just saying that I hope he's having fun.
