Does divorce occur due to obsessive thoughts regarding allusive phrases, such as pressing words on a mobile phone or pointing to them, or when the word "mobile phone" is mentioned with the intention of the wife, or when the phone is requested with the intention of the wife, or when listening to songs with the intention of allusive phrases and ẓihār?

Your pressing the keys of your mobile phone to perform certain functions has no relation to divorce. You are advised to turn away from the whispers of divorce and instead engage in the remembrance of Allah, recite the Quran, and learn what benefits you in matters of religion and worldly life. You can review the fatwas related to treating obsessions and listening to music.
