Haven't heard from him after first date, should I let it go?

[flow28]

Been on a date recently, we went to a restaurant. He paid and opened the doors for me. He asked me before the date if I'd prefer a hug as a greeting, just a handshake, or no touch at all as he wanted me to feel comfortable. We went for quite a long walk afterwards. We hugged for hello and goodbye. After we parted he texted me saying to let him know when I'm home. I let him know. The next day I decided to text him. I said I had a good time and added a question about whether he logged me out of a job search website (he let me use his laptop to edit my resume as a small favour), as I forgot to log out. He reacted with a heart emoji to the 'good time' bit and said he logged me out. Since then we've been silent for like four days already. He's been active on social media. I wanna see him again but I don't know if he wants to. Should I just leave it? Some people advice me to message him again but I'm not convinced that's a good idea..

Chances are he isn't interested but just in case contact him again and bring up getting together again and see how/if he replies. You'll have your answer then.

He isn't interested in a second date. 

Keep it moving forward. 

Edited to add: You didn't ask if anyone has any ideas why he isn't interested but if you are looking for guesses, there's primarily one- and only one main reason why a person isn't interested in a first date and to most experienced dates it's no surprise. Well it is a surprise, that's the whole point.
