Unfortunately you've fallen into the trap that naive girls fall into, even boys sometimes.Your not alone in this, I know it must be a terrible feeling. But regardless of how hard it is...ty and think of it as a positive experience, it will actually make you a stronger person if you learn from this mistake. Don't dwell on it, because that's not going to make any difference to the situation apart from making you feel worse than you already are. In a way, him being distant with you and pretty detached is him hinting to you that he doesn't want to go down that path although it is partly his responsibly for leading you on first. If you feel like you need closure to the situation which I'm sure you do as you must feel so confused as to why he's acting like this because he hasn't actually told you upfront then I would put your pride down and call him and just tell him exactly how you feel. Calling is much better than texting in situations as such. Trust me because if you keep your thoughts bottled up and you don't tell him every single thing on your mind eventually you won't be able to keep it in any longer... so somehow you'll feel the urge to tell him and it will happen unexpectedly.
Stay strong and remember everything happens for a reason. Take it as a lesson learnt, you shouldn't feel like you have degraded your self. You are still full on worth. Oh and you never gave it to him easy, he had to get close to you first, talk to you everyday. Keep your head high.
