Well, I guess all the above solutions cannot help the loss of the real CD collection. They all describe just the keeping of musical data - not the medium itself and all the memories coming with it. So I'd suggest you sit down and really sort out who's gonna get which. It might come down to a couple of CDs where it is impossible to compromise but in most cases you'll beable to give away or keep the respective CD. In the end both of you will have at least half of the common memories (if desired at all!) and it's a fair agreement. For the rest of the CDs go for a decent hard disc and iTunes as described above. I'd suggest to rip NOT data reduced!
All the best for both of you!
