I completely understand where you’re coming from with this question, and I really appreciate that you’re asking it with genuine curiosity. It’s definitely a complex issue, and I’d like to try and explain. I do realise that some of this may come across as sensitive, but please know that my intention is not to offend anyone, so I apologise in advance if anything does.
From my perspective, a person first establishes whether they believe in God or not, and whether they believe the Quran is the truth. Once that belief is confirmed, it brings with it a sense of trust in God’s wisdom and guidance for how we live, even if we don’t always fully understand the reasons behind every aspect. If we have already established we believe the religion to be true, then we accept that these are God’s commands, and we try to follow them to the best of our ability.
If someone were to focus on the rules and regulations first, without first establishing their belief, I can see how it would feel restrictive or even unfair. It’s only after you believe that you begin to understand the purpose behind the way of life that God has set out for us, and you have faith and trust in His guidance.
Islam teaches that character and how we treat others is incredibly important, and no form of abuse is ever justified in the eyes of God. Unfortunately, there are Muslim men who abuse their positions, or conflate ‘culture’ with the actual teachings of Islam. I’ve been in a similar situation to the OP and now feel that, if I were to seek a new relationship, it will never be with men from certain cultures where attitudes towards women are un-Islamic and harsh.
From the Islamic perspective, a believer in God is considered better than someone who rejects Him. I understand that this might sound offensive, but I’m not trying to offend—just trying to clarify the doctrine. However, in Islam, a person is not a Muslim simply because she or he claims to be. It is not about the ‘label’ - it’s their actions and beliefs that determine whether they truly are believers, and it is these actions and beliefs that will determine their standing with God.
A person who is not Muslim but demonstrates good character - someone who is kind, polite, doesn’t harm others, and lives with integrity - will certainly be rewarded in life by God for their good actions.
