So, inappropriateness of thread title aside, I need breakup advice. I am sure you will all be shocked to learn that I have never really instigated a breakup before, but and thinking that I need to now.

We have been dating for several months now, although the status of the "relationship" is a bit in flux. For much of the time, it has been "casual" at her suggestion, with no objection from me. But even though I like her, enjoy hanging out with her, and we are compatible on quite a few levels, I don't think I have serious feelings for her. I don't know exactly where she is, although several month ago she actually said that she thought "she needs to be single again." The intervening sex and hanging out rather muddled what that meant, thus my confusion.

Anyway, how do you break up with someone with whom you are at most "casual" by agreement, but yet more than casual in practice (i.e., hanging out/hooking up every weekend, and with some frequency during the week)?

Of course, the added complication is that we work for the same employer. We don't generally work together, although that is a possibility. Hopefully it won't be a big deal as I don't think there are any hard feelings (at least yet), but nonetheless, it is a complication.

Any suggestions would be appreciated.
