Free will

So if God knows everything, does he knows what choices we'll make before we make them? because if he does do we really have free will? I think God sees all the possible realities that can be made by every possible choice we make, and so he is never surprised by what decisions we make, because he has accepted the fact that we may do that, whether or not he knows which plane of reality we will choose I don't know. Honestly, I don't think this is an issue of great importance to my faith right now, it may be an issue I look at in the future but right now there are many more important issues I feel I should look at first. I think it is important to ration how many questions we take on at a time and sort out what we believe on the issues we currently are thinking about before moving on to taking on more questions. If we try to question everything at once we won't ever find the answers to everything. At the same time I think its important to always be willing to question anything so that we don't become too set on our own opinions that we are ignorant of other ideas.
