Why am I in love triangle with that man who I am very much in love with?

I have a long distance relationship with that guy.. I live in Ky and He lives in Md. He s very easygoing and sensitive. He said he loves me very much, but he s still shielding up and not ready for relationship. he says he s interested in dating me for now. I just found out that he also sees another woman in Md. I feel like I am so desperate to have him. I admit i know he s the one for me without doubt, but am I wrong?? Because he still sees someone else also. Each time we meet again, the sparks are still there between us. But he won't admit that he is in love with me. Why?? Since the long distance relationship I am experiencing, so that means I can't question my suspects with him if he s seeing that woman or not. Do you think once he sees that woman and the sparks could be lost when we meet again next time? Or the sparks would still be always there between us no matters what happen?
