<human>: So, we've worked together for over a year now.  When we first met he had a girlfriend of two years and I was newly single.  He and his gf broke up last November and he's been showing weird signs of depression every now and then.

He's always been very sweet and we occasionally trade books.  During the holiday season we went to a party together and ended up making out, but nothing more than that.  We met up and made out one other time since then.

Since then we've made plans to get together (he's initiated most of these), but he always ends up bailing for one reason or another (sick, OT at work, with family, etc.)

The problem is I know another girl we work with has a thing for him (even though he doesn't 'like' her - his words) I actually don't know for sure if they have a thing.

STILL he occasionally mentions that we should get together and 'hang out' but I'm very standoffish about it now.

Is this guy trying to play me?  Is he still bent out of shape from his long term relationship?  How can I ask him to be straight up honest with me?  And I'm trying to avoid the other girl, because she's not particularly nice and I'm really not interested in making an enemy.  

A few other weird things happened, most notably him showing up as a match on my now deleted OKCupid account.  Neither of us said anything about that. >_>

Provide a brief overview of the text.
<bot>: coworker and I have had sexual tension and while he 'wants' to hang out, he's very flakey.  Wtf is going on?
