Exactly the same situation happened to me - we were co-workers (I can’t bring myself to do the cow thing); we stayed friendly and enjoyed each other’s company, but the worst thing I ever did was put my life on hold to see if she would ‘come round’. Of course she didn’t. To steal shamelessly from every other poster: move on.
BTW, there’s another thread somewhere about how rare it is for all dopers to agree on something - up to now there’s unanimity on this one - does this tell you something?
