My husband is logging into my iPhone account and receiving my text and interfering with my calls

Immediately stop sharing an Apple ID. Each person, regardless of age, needs her/his own, unique Apple ID.

The person acquiring the new ID must thoroughly cleanse her/his Apple device(s) before “moving in” using the new ID as follows:

What is Family Sharing? - Apple Support

Without knowing a lot more about the details we can't give full advice. However, the most frequent cause for problems like this is two humans sharing a single Apple ID, and as far as their devices know they are the same person just using two different phones. This is almost always due to a well meaning but misguided attempt to share data like photos, or simply that one user has upgraded and passed their old device to their partner without a full reset.

The correct methods for Apple ID are either:

Each human has their own unique standalone Apple ID, which can be shared between all the devices that single human owns

-or-

Use Family Sharing if it is desired to share data automatically between family members.

Unfortunately if the problem is multiple users on a single ID, it is likely one of you would need to completely erase their iPhone and start by setting up again from scratch with a new Apple ID

There is another less common and less friendly possibility which might be suggested by your post, that you each already have your own Apple ID but your husband knows the login credentials for your ID. In that case (if you consider it safe to do so) you could consider simply changing the password for your Apple ID.

Start by reading the following document:

Personal Safety User Guide - Apple Support

There’s a PDF of the whole document linked at the bottom.

You will want to use the Safety Check feature, as well as the three checklists listed on that webpage.

You will also want to reset your passwords including the password to your Apple ID (as linked in earlier replies), and change the passwords to your password-reset paths such as your mail account(s) and your cellular provider support PIN or passcode, and enable two-factor authentication on your Apple ID. Probably also add trusted associates as recovery contacts.

Unauthorized access can be a civil or criminal matter in various jurisdictions. That can mean discussions with a lawyer or victims’ rights advocate in your area.
