I feel like a piece of shit

I’m seeing a guy from last 2 months almost. We are not in a relationship but we talk a lot. He lives in a different city but he came to see me once and I went to see him as well. We had a great time together. But now when I asked him to meet again he said he will meet when he will feel like and till that time I’m allowed to see anyone. I don’t know what should I do in this case. Please advice me I don’t want to feel like a piece of shit.
