Why am I seeing my wifes call history and missed calls on my iphone?

The "issue" is a direct result of sharing an iCloud account. Don't do that. There is no reason to do that. iCloud accounts are not meant to be shared. There are ways to work around it, but those are band-aids.

Solution:
Go to Settings > Click on your name on the top of Settings > click on iCloud > scroll down to iCloud Drive and turn off.

you will need to turn off iCloud Drive on either one of the phones, not necessarily both.

I wish Apple would weigh in on this problem. It is clear many people are having the same issue!!

You will not see Apple "weigh in" on this here, since this is a user to user support forum. However, as KiltedTim indicated, it has to do with your iCloud ID, being on the same Wi-Fi and Continuity. Apple has provided information about continuity and here is a link. Connect your iPhone, iPad, iPod touch, and Mac using Continuity - Apple Support

Can't be the problem. It just started happening 3 days ago and my wife only Sees mine, I don't see hers. iCloud has been out for a while now and it hasn't been an issue before.

Well, whether you think it is the problem or not, that is why it is happening. It has to do with being on the same Wi-Fi, with the same iCloud ID and having the numbers selected in Settings. While iCloud has been out for a while, continuity is new.

OK, then. You flatly reject the answer you got from multiple forum members. That won't alter reality in any way. Feel free to continue beating your head agains the wall.

Continunity didnt come out 3 days ago. and we have had the same Icloud account, on the same wifi, with her number selected on her phone and my number selected on my phone. So why know would it be a problem?

So here is my question. Haven't seen this anywhere yet. The only thing we use an icloud account for is itunes and apps. Facetime, SMS, and others are per persons iCloud account. This way we share the same apps and music but can each facetime/message each other. Each persons device (we all have iphone and an ipad) are setup with their personal iCloud account and continuity is working just fine between them. This history issue has never happened until a couple weeks ago.

HAving the same problem, so have turned off iCloud on Wife's phone, now she has lost photo stream and find my phone features,all was fine untill two days ago, I have changed no settings.

Wrong. Wrong, wrong, and wrong. You use an Apple ID for iTunes and Apps. iCloud is a different animal entirely. An iCloud account is tied to an Apple ID, but it is NOT the same thing.

iCloud is used for syncing information (contacts, calendars, etc.) among multiple devices via the cloud. It is also used for services like FaceTime, and iMessage, PhotoStream, as well as FindMyiPhone and I'm sure a few other things I'm forgetting right now.

You do NOT need to set up the same iCloud account on multiple devices in order to access content purchased from iTunes and the app store using a common ID. There are multiple ways to deal with that.

iCloud accounts are personal. They should NOT be shared.

You can turn iCloud back on. All you need to do is go to Settings>FaceTime>iPhone Cellular Calls>OFF. You will be able to turn your iCloud and Photo Stream back on again.

This is NOT true. I am seeing my daughter's calls, and while we share an icloud account (for several good reasons), she is 1700 miles away from me!
