There's a guy I work with that I've become interested in, and he seems interested too, but...I'm not sure. He had a girlfriend a while back and when he got in a relationship with her he stopped talking to me as much, limited eye contact, etc. Then I noticed him being more friendly again recently, and found out they broke up. (I've been a bit careful since he's probably in rebound right now..) He does things like:
*Say "Good job, (name), good job" over little things, like sweeping up something on the floor, etc. One time I was setting up the private dining room for a group the next day and he was sweeping the main restaurant, and he poked his head in on his way past to say that, then a few minutes later he came in to plug in the vacuum and said that again, then he walked over to me and started making conversation.
*Every time he walks past me, no matter how much space there is, he always brushes his shoulder against mine or comes close to it.
*He rarely talks to me if anyone else is present.
*Jokes around a lot so we end up bantering back and forth. One time I came into work a day I wasn't put on the schedule without meaning to, and he kept saying, "Man, (name), I can't believe it. Coming in on the wrong day..." I just looked at him and hit him with a rag I was holding, and he then chuckled and said he was just kidding.
*He came up to me recently half smiling and said "You don't have a boyfriend?" Now, the way he said it implied he knew I didn't, which he probably picked up on because last time we worked together a girl working with us ran up to me while he was present saying there were some "really cute guy customers that came in" and that I should go out front and "do my thing". Anyway, I told him I didn't have a bf, and he asked why not. I was debating how to respond, so I paused, and he said "No reason?" and I said "Yeah," and jokingly added "there must be something wrong with me". It ended there because our boss called him over for something.
On the other hand, he can be moody. There are times he isn't very friendly unless I put effort into it. And some days all we say to each other is hi and bye. So is he just a bit of a flirt or is he actually interested? He can be flirty with a couple other girls too, not just me, which is what makes me wonder. He usually does initiate interaction, so I've been trying to initiate more myself to give him the idea I am interested. I don't want to flat out say so, so I'm trying a more subtle approach to tip him off, but I'm more or less new to flirting...so any advice on how to do so would also be appreciated.
