Short answer: Nope, Y will not even know you added her. Long answer: When you add someone's phone number to your contacts, Whatsapp will automatically detect those that have a Whatsapp account and show up there, BUT if those contacts have you on their list or not is irrelevant at this point.
In WhatsApp Settings > Account > Privacy, there is option to set who can see your dp(profile pic), status, or last seen. If he has set his dp to be visible to everyone then you can see his dp even if you are not in his contacts list, just by saving his number in your phonebook.
If you can't see someone else's last seen, profile photo, about, status, or read receipts, it may be due to one of the following: Your contact has changed their privacy settings to "Nobody". You have changed your last seen privacy settings to "Nobody". Your contact hasn't set a profile photo.
Anyone who is able to read your message has your number in their contacts, so you should see the name of the contact whom you know has your phone number here. Keep in mind that a contact who has your phone number but rarely uses WhatsApp will not show up in the "READ BY" section until the next time they use WhatsApp.
Using the Change Number feature in WhatsApp will migrate your profile information, groups and settings from your old phone number to your new phone number. It will also delete the account linked with your old phone number, so your contacts can no longer see your old phone number in their WhatsApp contact list.
Unfortunately, there is no way to hide your phone number on WhatsApp. The app requires your valid phone number to let you login into the service. But that doesn't mean you can't hide your current number from your contacts. There is a trick you can use to hide your current phone number on WhatsApp.
The only way that someone can see if you've checked their WhatsApp Last Seen status often is if the person has enabled WhatsApp+. The WhatsApp+ feature lets you get a pop-up that gives a notification saying “[Your_Friend] Online” if your friend is online, and if they've seen your profile in the last 30 minutes.
In settings: For every Android phone, regardless of manufacturer, you'll be able to find your phone number if you go to Settings > About Phone or About Device > Status > My phone number. Some Android phones will have SIM or SIM card status listed within Status.
If someone doesn't have my number, will he or she be able to see my WhatsApp status? Nope! You can view a person's status only if you and the other person have saved each other's number. To check this, go to Whats app>Settings>Account>Privacy>Tap on 'About'.
You can also choose to notify contacts who you have a chat with. Simply, the user has to select the Change Number option in WhatsApp Settings -> Account. After inserting the required old and new phone numbers, WhatsApp will ask which contacts have to be notified about your new number.
