What should I do? Let go and move on or wait?

Ok. I am in love with this guy he loves me too. He is trying not to. He says he dont care when he does. But he likes another girl. He says their only friends though. And ok I believe him. Just I get jealous. And I think he’s scared to show his love for me he never puts it in his pm or anything he only tells me, he hasnt told his friends he loves me or anything. He always puts this other girls name in his pm and his friends all know about her. So does he love me or not? He’s not talking to me for awhile now. I said to him I dont know how I feel for him anymore cause he keeps pushing me away he didnt like it when I said that and he wont talk to me now he dont wanna. He said he wants a months break but he always does this. He dont like me talking to any guys older than him 17 years old, he is 2years older than me but idont care. He always seems to talk about sex and stuff he talks about sex to this other girl too. He gave me a necklace for x-mas says its his heart. Then he asks for it back cause he wants to give it to mel the girl he likes. Their ment to be best friends. But they only know each other from the net. He says their only friends but idont know if they are he seems to listen to her all the time cause she says im no good for him and hes listening he cant make up his own mind. Now im only 15 and I love him sooo much I care about him so much but does he seem worth it? I wanna be with him so much I said I’ll wait for him or am I wasting my life? Should I let go and move on? Help please
