I am going out with a group of friends this Saturday. Last time I went out with this group one of the guys in the group let me know he was interested in me. I after that night we spent a lot of time flirting and even hooked up once. But I backed away afterwards, and pushed him away. We have since ended up working together. We have talked but it's different, sometimes we flirt and sometimes the looks can intense. But I try to keep it business. My career is important and high profile plus I am moving up fast, so professionally I didn't want to complicate things. I have been missing him and the way things were. I like him and regret my decision. How can I find out how he feels with out looking desperate, or totally fickle.
I wouldn't call it desperate or fickle, it sounds like you believe you made a mistake by pushing this man away. If you're willing to possibly create complications in the work place, then I suggest going to him and saying, "Hey, when we first met I really liked you, but I got scared and pushed you away, I'm really sorry. I was wondering if we could start over."
There's nothing to be ashamed of. If he can't accept the apology, then he probably isn't worth your time :)
