^I have a question, I want to say I hope it's not offensive to you firstly.
I've read the quran in English with my exDH many times and it states that there is no book but the quran (that you need to follow) and everything a Muslim needs to do/know is in the Quran, so why do a lot of Muslims follow hadiths(books written many hundreds of years after the quran was sent down)?^
That is a very good question, and definitely not offensive!
Hadiths are collections of what the Prophet Muhammad said. These were recorded down in his life and after it. The hadith books were compiled together around 200 years after his death, but they were extremely strict rules about which sayings of his were included, as obviously time had passed (and people do make things up or mishear), and despite being written down, someone could have added or edited the sayings. However, the rules were very very stringent about what would be included in the major hadith books. For each of the sayings in that book, all the narrators had to be recorded and each narrator's profile was checked to see if they were honest people. So each saying goes something like this: I heard from X who heard from X who heard from X who was sitting next to the Prophet in the mosque and heard Prophet Muhammad say: "The best among you is the best towards his wife ... (just an example)." The compiler did a multtiude of things to ensure its authenticity, including checking the profiles of each of these people in this chain. If there was ever doubt, he would not include this saying in his book. For example:
Imam Bukhari (the famous hadith compiler) traveled to meet a man in order to take hadith from him. But he saw this man calling his horse with an empty vessel in his hand, as if there was food in that vessel, moving it in order for the horse to come near so he can grab the horse. So Imam Bukahri asked him, “What is in that vessel?” And the man said, “Nothing.” Then Imam Bukhari said, “By Allaah, I will not take hadith from you, because you are a liar.”
Similarly, each hadith had to be narrated by multiple all authentic people. So if he found one person saying this is what the Prophet said, and despite having sound people in that chain, because it is just by one person, he would not include it in the hadith book. It would have to be a hadith that he heard directly from many people with all souund narrations, and it was a well known hadith too. And they had to fulfill ALL of the above criteria (and others too, I can't remember at the top of my head) to be included in the hadith book, and there were very very stringent rules, and the chains (and the hadith content itself) are constantly academically critiqued (and the critique is always welcomed), even now, almost 12,000 years later.
Coming back to your original question as to why Muslims follow the hadiths (the prophet's sayings) as well as the Qur'an is because a) the prophet's sayings explain the Qur'an (and never contradict them), b) there are some things that are explained in the Prophet's sayings and not in the Qur'an, like how exactly to pray salah (the 5 daily prayers). So you can't understand the Qur'an without hadith, and c) God commanded Muslims in the Qur'an to follow the Prophet:
"Say, [O Muhammad], "If you should love Allah , then follow me, [so] Allah will love you and forgive you your sins. And Allah is Forgiving and Merciful." (Surah 3:31)
Sorry I went on a bit
