Allah swt does not go through emotional states like humans do. If He did, then he would be comparable to his creation which is impossible. Therefore, scholars interpret Allah's love and pleasure as his reward to us, and his anger, as his punishment and chastisement as found in narrations. We can also see the love of Allah for us in his actions by the blessings he has given us and through creation.
Please read the following tradition from Kitab Al-Tawhid of Sheikh Saduq which may help you understand this matter more:
A man asked Abu `Abd Allah al-Sadiq (AS) whether Allah, the Blessed and Exalted, feels pleasure or anger. Thus, he (AS) replied, "Yes; however, it is not like the pleasure or anger found in created beings. Unlike human beings, pleasure and anger do not change Allah from one emotional state to another. Human beings are operated and composed. Things can affect human beings, while things cannot affect our Creator. He is One in Essence and Concept. Thus, His Pleasure is His Reward, and His Anger is His Punishment, without anything interfering with Him so as to ridicule Him and transform Him from one sate to another. Emotional changes are an attribute of the crated, the helpless, and the needy. While He, the Blessed and Exalted, is the Supreme and the Honorable, who has no need from any of His Creation although all of His Creation is in need of Him. Verily, He created everything without any need to create or innovate."
May Allah grant you success
