If God knows the future, why did he let you get into a relationship with someone that seemed great at first but later on they changed into a completely different person?

Put simply, according to Hebrews 12:7-8, if you are a true Christian – then yes, God is disciplining you because he disciplines all true Christians. But there are seasons in life where God is specifically disciplining us in a more intense way and in a particular area of our life to accomplish a specific purpose.
