Date info advice!

So I met this guy online we finally met in person. He's a senior in high school and I'm a freshmen in college. He's super sweet and I want to get to know him. We decided to be friends with some benefits because we're so busy with school but we have those feelings for each other. It's so hard because I want his attention but he isn't always there. He told me he doesn't really like technology that much and I agree because I can be the same way. But when he's able to keep his Instagram and facebook updated its kinda annoying. I think some of it is that he has to record his life on the social media and have that alternate social media life that most high schoolers have(if that makes sense... Basically addicted to social media to make them seem cooler that what they are.... If this makes any sense haha) I'm just dying to have his attention and Ive been avoiding texting him first and he messaged me yesterday and the day before he let me know that he was having phone troubles which I was shocked to have him make a point to communicate that to me through social media because when we first started to talk he disappeared on me and he just came back and I chewed his ass out and told him I'll give him a second chance but he has to communicate with me. Just I don't know if he isn't giving me the attention because we are casually dating and he's use to hanging with his friends/doesn't see me everyday at school like his other friends. Does anyone have advice on how to handle this? I don't have older sisters to talk to and I just started dating a month ago so I don't know what to do/ handle these situations and I feel like I'm being clingy even though I've been holding out for him to text me and I'll take time to reply back. I had a dream that all my teeth fell out last night (the first time I've ever had this dream) and I guess it means that I feel like I've lost control of something and honestly I feel like I have no control In This situation and I don't want another guy to just disappear on me again and hurt me. I just really want this to work out and hopefully become more.  Help!
