Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
Merging can happen if the same Apple ID is logged in on both phones.
To reverse this, tap Settings > iCloud and log out, then log in again using your own Apple ID.
No worries, let me know if logging out of the Apple ID on your phone works...
I'm still here - so what is the status of your phone now that you have logged your phone out of your husband's account?
Did he have access to your phone, or could he have guessed the password?
Ok, so have you gone to Settings > iCloud on your phone?
What account is showing there? Yours or his?
That's ok, take your time and let me know how it goes :)
Yes I am working 7 days a week, you can contact me any time and I'll get back to you as soon as possible.
So were you able to log out of his iCloud account on your phone?
You won't need his password, just log out of his account....
Has that resolved the issue for you?
Ok, again try logging out of iTunes:
You are welcome, it was a pleasure to help you today :)
