Search Results: smell down there

So to start off I had befriended a this guy at work and we would casually talk between shifts in the morning there was always casual flirty but nothing serious because we were both in a relationship. We work in a hotel and the guys mother came into town and he got her a room here. I work the graveyard shift and he works mornings. He ended up drinking about a bottle of wine and came down to the desk and talked to me for hours. He and his girlfriend had only been broken up for days and I was still with my guy so I ended up declining him but I still flirted with him.
Now we don't talk much anymore and he's back with his girlfriend, but the other day he told my my hair smelled nice after he hugged me and I feel like there is some sort of tension in the air or maybe because It's because over the past 3 months I've started having feelings for him. Plus he apologized the next day and told me maybe a different time or place. WHAT DOES THAT MEAN? Like he'd be interested in going on a date or hooking up?
I also recently moved to a new house and it's actually in the same neighborhood as his (unintentional) and I saw him drive by so I casually asked him about what the neighborhood was like and now When he drives by my house he drives by slow and waves. Like significantly slower than the other traffic.
As shallow as it sounds I know he's in a relationship and so am I but after that one night of just talking I haven't been able to get him out my head and I know its not right to my boyfriend but I haven't left him cause I love him, I'm just not in love with him.
Do you think I would have a chance with this other man (relationship not a hookup)? Do you think he was just trying to get in my pants? or could him drinking that night could have been the cause of all of this?
So many questions run through my mind.
If there is a chance he's interested what could I do to grab his attention and make him think about me long after I'm gone in a work setting?
