I met someone at work a few months back. He works in a different department, but often comes around to chat with people. He’s been talking to me a lot, trying to get to know me, and I’ve noticed he seems different to me than to other girls. He talks about personal things sometimes, and lately has been saying some sexual/perverted things. Also, whenever he sees me or talks to me, he brushes his hand against my arm or nudges me.

There are times, however, when he ignores me — when he’s with other people (male or female), sometimes he pretends I’m not there and pretends he isn’t looking at me. I haven’t known him for that long, but it really confuses me, because it would seem as though he likes me, or at least wants to have sex with me. But then there are moments when he acts like he has a problem with me.

He teases often in a friendly way, but sometimes he is just mean, and I really don’t know what to think about it. Somebody said it might just be that he wants to have sex, but doesn’t want to tell me, as it might be inappropriate. I’m not sure what to believe.
