So I am seeing/dating this guy for about four months. We hung out for a couple times, had dinner, watched movies, etc. In the beginning, he would text me everyday and call me at least once every other day even though he said he was busy to see how things are going for me. He liked me to keep his company when he is studying at home, so he would come over (the other end of town) to pick me up to hang out at his house when he is doing homework. I thought we had some great time together... emotionally and physically. Lately (2 weeks ago), he has been acting differently, he stopped texting and calling... though, he is still replying to my text/call/emails... It's just not the same anymore. I asked him what's wrong and he told me he has been busy. Last week, he suggested me to go over to his place again because he doesn't have school that day... then, the next morning he texted me and told me he needed to study and didn't have time to see me. So, it's like he kept on being hot and cold. He doesn't want me to accompany him during his homework time anymore. Ever since that day, we haven't talked... so last weekend, I decided to write him an email and told him I don't like to have this uncertain feeling about our "relationship"... and it took me almost a week to reply, all he wrote in the email was "I'm busy =) ttyl"
Is this the end of the story? What's going on?
