Found my perfect match, but don't know if I like them that much?

Okay, so I found someone who I have been spending a lot of time with recently who is basically perfect for me based off of the way we interact. I've had a lot of experience with dating so I know what I look for and need in a guy. I was automatically attracted to him when my friend introduced us, but we have so much emotionally and personality wise in common I can't tell if he would be better as a friend or a partner. We have very compatible zodiac signs. I really enjoy spending time with this person and I love how much we have in common and how we react together. But, I just don't know after spending more time with him if I really feel romantically about him. Could it be something that grows over time? It's almost like he's too perfect and it's setting me off. Because I know we would be a great couple, have lots of adventures together, always get along and such. It's almost the sort of thing where I want to be with him because he's extremely practical, right for me, and incredibly romantic and sweet. But, I'm having a hard time now being that romantically attracted to him? I hope I'm not confusing anyone who reads this. I feel like if I don't go for him then I'm missing out on someone who I may never find again, but if I go for him and I continue to not gain romantic feelings for him it may break his heart in the long run because I could only be friends. Advice anyone? Thank you!
