There is a guy at work that has been msg me on IM. He is really flirty with me and the other day he flat out told me that he knows I like him, but of course I denied it. Sometimes he can be really flirty and interested and sometimes he acts really distant and it almost feels like he is ignoring me. I know he has an on and off gf, but he drunk texted me one night asking me to hang out. He said he was really busy at work and he gets so caught up in it that it's the reason he becomes distant. Does it sound like he likes me or just playing games?
