Is he who loves a created being as much as or more than he loves the Creator considered a disbeliever, regardless of whether his love for the created being is a love of worship or not? What is the ruling on one who loves a created being more than the Creator? Have scholars reached a consensus on declaring as a disbeliever one who does not love Allah but does not hate Him, believes in what the Messenger brought, and obeys him? What is the meaning of "If a lover reaches a degree of love such that the love and obedience of his beloved causes him to disobey Allah, then he has committed shirk"? And what is the ruling on a Muslim woman who marries a Christian man out of love for him?

It appears you are experiencing whispers (waswas) concerning disbelief (kufr) and polytheism (shirk). To put your mind at ease, you must disregard these whispers. The mere love of a creature that leads to disobedience of Allah does not necessarily entail disbelief. Prioritizing the love of other than Allah over the love of Allah is not disbelief in all cases. Nevertheless, faith is not valid without love for Allah. So, if a heart is devoid of love for Allah, faith is negated from it, and this is disbelief. As for your statement that if love reaches a degree where it causes its owner to fall into disobedience of Allah, then he has committed shirk, the mere love that leads to disobedience of Allah does not necessarily entail disbelief.
