How do I move on from him?

I'm in love and the person I'm in love with seemed like he was genuinely in love with me too but lately he hasn't called or texted me for a month maybe he got grounded or something but I'm worried because this isn't normal for him because he's the type to call and text everyday without fail and I always catch on to the signs of someone losing feelings or cheating and I never got any signs or anything being wrong. It's been 5 weeks now and If he doesn't call soon I will move on but how??? I need advice!!!!
