You must always ask questions. Don't be shy. If you want to know if they are a happy person or do they have a temper.
Ask what do you enjoy? What do you do when you get angry(driving, or if you don't get your way?)
Make a list! 25 -100 questions You need to know.
I hope this helps.
salams sister.there is no way in knowing if someone is good and honest or not,all we can do when we meet someone is make duaa to Allah and ask to bring this person close to me if they are good or take them away if they are not.we must have faith in Allah that he will send the right people in our lives.it is said in the holy quaran.the good is for the good and the bad is for the bad.and sometimes Allah will test a person and see if we will rely on him and get closer or move away.no matter how good someone may seem to be ask Allah for guidence.and if someone may seem not quite right also do the same.we can not judge only Allah can.just believe in Allah and have faith and don't ever just settle or lower your standards.
