I'm so thrilled for you and totally understand why you would go the exclusive route even a few dates in. Like DV said, I'm a one at a time kind of girl, so if I had a few successful dates, I would want to go ahead and just date that one person until we either decided to continue to something more serious or decided to part ways. Now, I don't think (and because we are similar, I think you'll agree) that it means that you are rushing to ILU or anything like that. You are just a mature woman who has no interest in bouncing back and forth among several different options. Stick with one option, see where it goes, then act accordingly. I wouldn't have a problem with anyone, man or woman, doing this. My problem with this is when it rushes to ILU whether you feel it or not, in response to the other person saying it.
