I don't know what's going on between me and her

You are all over the place.

First off, don't sleep with people you work with!

But now that you are, or at least you were, let's examine the facts, shall we?

You kiss occasionally, albeit not passionately that often. You sleep together once per month or so. This is far from being a relationship; it sounds a lot more like an itch being scratched when nothing better is available.

You claim that neither of you want a relationship, and then you fret about her possibly leading you on. That does not happen in non-relationships. You claim you are getting closer all the time, yet you later in the same sentence claim that the window of opportunity for an intimate relationship has already shut.

Sounds like you talk but never go anywhere. No one seems to be spending any money except, perhaps (hopefully, as I doubt there's exclusivity in the bedroom), to purchase condoms.

You do not have a relationship. You have a **** buddy. Do not pretend this is anything but that. Forget your deep and allegedly meaningful conversations. I am not saying that you need to empty your wallet for this woman but the fact that no money is being spent, and you are not going anywhere together, those are indicators about value. Neither of you value this much.

Quit kidding yourself. If she didn't seem so hot to you, you'd never stand for this kind of bullshit.

Your right I'm gunna back off talking to her quite so much, she is cool so I won't be ignoring her but there are a lot of fish in the sea I'm gunna get back to it.
