Boy problems please help :')

Hi, there. I'm new and this is my first post I hope I've found the right thread and all.

I'm having some boy troubles, I've never been in a proper relationship before so this is my first time having to deal with something like this. We met a few months ago and a few weeks later we kinda started making out and stuff. He's not allowed to date until he's older and done with school so we had to keep it a secret. This went on for a little while but now he's just suddenly not visiting or talking to me anymore. I think this is my fault because I can be really clingy and also kinda shy, I feel like I either scared him away or made him frustrated with me. I'm not sure how I should feel or what I should do if anything. He's the first person I've properly kissed, touched etc. So I think I have a good reason to be at least a little upset about this. Thing is I also felt like this wasn't going to last very long but I don't want to be alone, I don't have friends or anyone to comfort me. What do I do? Should I try say something or should I just try and accept this and move on?

I feel really stupid and guilty talking about this so I'm sorry if my post is a little chaotic :')
