Phone is hacked

It is unlikely that your phone was hacked. What is more likely based on what you're describing is that your husband has access to your accounts. See here:

If you think your Apple ID has been compromised - Apple Support

You should also change the passwords for any other accounts you have like Facebook, LinkedIn, Twitter.

I do keep changing my password but it keeps happening.

If it's Facebook and Facebook Messenger that you're asking about, you'll need to contact Facebook support for additional help.

Messenger is a facebook product/service. Secure your account.
