I went out on a 1st date with this guy and we stayed together for almost 6 hours. The conversation was amazing and it never felt awkward. I instantly felt comfortable with him. The issue is that I didn’t feel sexual interest from him (e.g. body language) and I didn’t feel like hugging or kissing him before I left. He texted 3 days later to see if we could get together again and I said I really enjoyed the date and thanked him for dinner, but I see him as a friend. He was kind and agreed we can be friends and still hangout. Problem is, I really regret it since I find myself thinking about him often and the tiny cute things he did on the date. What should I do?
