Ok, so basically, my girlfriend (now ex) and I broke up for good last week. And it wasn't really a rebound thing, but the very same day my ex and I broke up, this girl from work called me up. We ended up talking for about 2 hours that night (didn't mention me and my girl breaking up at all). Everything was cool. She's cool, not the best looks, decent body, and basically, I could tell she was interested in me from the beginning (was working with her for a month). So long story short, we hook up, and had a make-out session the first night, only reason we didn't screw was cause I didn't think it was going to be that easy so I didn't bring any condoms, but uhh...the next night, I had some, so we did it.
It was great and all, and we both knew in the beginning that I wasn't trying to get into a relationship. That and the fact that she has a boyfriend of 4 years or whatever. Sooo basically two weeks has gone by now, and in the first week, we did it every other day and then my work schedule got switched to B-Shift, from A-Shift. And now, she's acting like she's getting addicted to me (which I said in the beginning neither of us wanted) and she's wanting to see me every day now. I had a bad feeling going into it in the beginning, but now I'm slowly trying to get out of it.
She is begging for me to come over tonight after work (12:30pm), but I'm not going...I'm "sleepy"...really gonna go home and play Oblivion.

And we're supposed to be going to a movie tomorrow sometime, but even that I really don't wanna go cause she's gonna want me to go to work on her. And I know she's gotten attached to me now. So do I just tell her straight up? Which would be easy if she didn't work with me...and actually she is somewhat above me, I'm a level 1 analyst she is level 2 and she's 27. So what do you guys think?
