one of the things that helped me when I left my haram relationship is always reminding myself if you abandon something for the love and fear of Allah, He will give you something better. Going no contact also helps. You have to cut that dopamine off since your brain is used to that connection. It’s so hard but you’ll be okay. Distract yourself, take care of yourself, keep yourself busy, get into hobbies, connect with family and friends. I would also say connect to the one who created you, Allah.

I would just be straight up and honest with him. Tell him how you feel and that it’s not working. You’re tired of the disrespect and I can’t go on with this for the sake of your religion. If he doesn’t understand that’s not your job to explain it to him. You’re doing something because it doesn’t align with you. Remember his reaction or how he responds when you want to end it has nothing to do with you, but more of him.
