Should i dump my boyfriend?

My boyfriend and i have been together a few weeks. -we go to different schools and live on opposite sides of town so we don't get to see each other very often- last week he slept over and it really great and he really acted like he liked me a lot and always told me that he liked me. We also used to Skype until 4 in the morning together. Lately, he hasn't been answering my texts or when he does then he's really dry. Then he texted me yesterday saying he was really horny and wanted to Skype. After we skyped, he stopped answering my texts again. I get really anxious when someone doesn't reply to my texts and he knows that. but also, on his phone he has a lot of unopened texts he just doesn't bother to open so maybe he hasn't realized that i texted him. i just don't want to bother him and text him a lot. What should i do? (please don't be rude. i really need answers)
