A guy from work is acting weird. He texts me everyday and we both share personal things with each other and our conversations can be really deep. We talk about everything including sex. We hung out a few times, we even drink beer at his home once. To be honest, he sometimes acts hot and cold and I can't get him. It's like something is happening between us but I can't get this too. I think he is conserned what others will tell if we are seen together. However, what could he possibly wants? A female friend, sex buddy, or nothing?
