You do seem to be going very full-on with the deep stuff, which is ok if you have a partner that feels equal about that but unfortunately a lot of people get turned off by that in the very beginning of a romance. I have a male friend that seems to scare chicks off as he very early on gets very deep and meaningful and I think until he finds someone as equally as deep right off he will struggle to connect with the vast majority of women. Not to say you have to change yourself or settle for someone that doesn't share common traits with you but my advice would be just to ease up on the heavy stuff until you get to know each other a bit better. Some people just like 'chit chat' and believe it or not you can learn a bit about someone through just chatting about general, mundane things. If you truly are like 'Sheldon' then you will have to make some minor adjustments to fit into the norm of society if you wish to progress with this girl (if you do want to date her). Again not saying you have to change however maybe just relax and bend your own rules a bit. If she is worth it then you should be able to reach a compromise with yourself to do this. Once you get to know each other then you can engage and connect on that deeper level. Hope this helps.
