I think that the biggest thing people need to think about when getting married is that love is a commitment, not a feeling. The whole "for better, for worse" thing is the most important part. The plus you two have on your side now, is the reality of knowing that "the worst" is not some intangible thing that may or may not happen. It is here. And it can happen to anyone (car wrecks, cancer, ms, etc.)- you (and she) just have a heads up on <i>this </i>one.
If she can commit to you, having a good idea (at least in her head <img src="i/expressions/face-icon-small-wink.gif" border="0"> ) all that may/will come your cf, and still is wanting to spend her life with you, then I say go for it. Only she knows what she can handle, and what she is willing to handle. My dh did tell me that he had to reconcile within himself the knowledge that he may be a young widower (along with everything else beforehand) and may end up a single parent if he married me- he was up to it, and we have been happily (for the most part-lol<img src="i/expressions/face-icon-small-wink.gif" border="0"> ) married 15 years with one 3 year old child. <img src="i/expressions/face-icon-small-smile.gif" border="0">
