texting/relationship advice

There's this guy I've been talking to and I like him a lot. Before we'd always be texting each other but recently he asked for a nude and I never texted back nor did I send him one (I've done it before but I didn't want to this time). I haven't heard from him again since then and I miss him. Should I text him? Should I wait to hear from him? Or should I let him go? I'll be moving in two days and I don't want to end things on a bad note and I don't know if he wanted a ldr. It seems like I'm the one who always tries to patch things up.
