Some recommendations:
1- Yes avoid seeing that with him. Be firm with him and tell him you will not sin because of his desires. This is a red line and won’t cross it anymore. So be firm with in hopes of him taking it more seriously.
2- Try to get him to see a therapist. This is an addiction and it does require therapy. Encourage him, but don’t sound like you are lecturing him or giving him orders because he might refuse. Be gentle and kind. Many times therapy works.
I also recommend you read the following:

3- Try to distract him with an activity that he likes. When you sense he wants to watch, see if you can distract him. Be creative and tell him instead of watching that, I’ll play a role for you (it might work). He might need new things to excite him.
4- Ask Allah to guide him. Read this Du’a daily:

5- When he is in a good, normal and understanding state, have a kind conversation with him. Tell him the way he compares you is very hurtful and insulting. Ask him, “Are you happy insulting me every time?” Let he know how serious his behavior is. But do this when he is in a good state and willing to listen.
May Allah guide him.
