Search Results: asking a guy to a dance

This guy and I met randomly at a bar 2 summers ago. We saw each other and danced and we clicked very well together. (My mom and friend were at that same bar and met this same guy before me at a party a month earlier, but he did not know my mom was my mom because she looks very young and they were talking as friends on facebook). As soon as me and my ex split I went out on a date with this guy from the bar and we seemed to get along very well and like each other, but he was wondering who my "friend" was and if she was really my mom, and he was telling me how my mom always kept on telling him to ask me out while I was with my ex bf who was abusive to me. We had a good date and he wanted to make me his gf. My phone had died and my mom was worried about me cuz it was getting late, and she called him up to ask him if I'm on my way home. The second time we met up he told me that he got annoyed by my mom and for her to never call him ever again - he told me this near the end of our date when we were talking. He wa salso asking me if I'm still with my ex or if I sneaked out and my mom was looking for me maybe. I reassured him that my mom is ok with me seeing him and that I'm not with my ex. Then again we met up for a 3rd date and things went well - he even lifted me up and kissed me goodnight before my bus came. But that night when I got home we texted each other and he sent me our photos of us together. Then I told him I can't wait for our next outing and then he told me "take it easy" and then he said good night.
After that we never met up in person ever again and he doesn't talk to me but he still has me as a friend on Facebook and Twitter and. He wished me a happy birthday last summer.

Why does he not talk to me anymore? Did he get annoyed or weirded out by my mom? Or did he think I was still taken by my ex? (P. s - he has told me that he's a virgin)
Is there a chance in the future for him and I to meet or talk again?
