Frustration

I am in a long distance relationship with a great guy for 2years, tho we have never actually met I can't help but have strong feelings for him, in April I asked him about seeing him in June, he'd said he'd get back to me about it but it's already the end of may and I feel weird if I bring it up again, I don't know if he's just scared to meet ? Or if he doesn't feel the same ? Or if there's someone else on his mind........
