I guess averyone's else summed it up pretty well as to repeat the same song again.

If you love her, and you understand her need for experiences as a valid one, you may think of making an arrangement: ask her to tell you how many time she will need to gather those experiences (let say, 3 months). Then call for a pause in the relationship and meet again after ending that period to talk and check out if your expectations finally meet. It's true, there would be a risk for her to get hook with another guy, and for her that you do the same.

Disregarding swinging, I know of a couple of couples who meet up an early stage in their lives (like, in high school), they wanted to be togheter but realized they needed other experiences before making the final choice, and they gave themselves time for this (in one case, a year, in the other, 6 years). They keep in touch, but meet again after that period and started over from the scratch. It is a valid (and wise) option, however, in those cases both sides agreed they BOTH wanted to have more experience, which doesn't seems to be this scenario.

In any case, unless at some point you share a minimal ground of expectations for the relationship and your life togheter, there wouldn't be any relationship to take care of, anyway.
