So you can't accept any of the evidences that show all of Revelation has been fulfilled, because you don't believe Jesus has returned yet. It's like a wall you've put up, that blocks all evidence until you see Jesus return. It's stifling you. This one dogmatic belief, is forcing you to see everything else in a certain light and it doesn't allow you to consider other possibilities. It's a shame really, because you're missing out on so much.
I've taken the exact opposite approach.
Your approach
I haven't found any evidence of his return, so therefore he must not have meant what he said about "this generation" and "what must soon take place", the "new Jerusalem", etc.
My approach
I believe he meant what he said about "this generation" and "what must soon take place", and the "new Jerusalem", so therefore I must be misunderstanding the return.
What's interesting, is that your approach requires an ego, which says that you can not be misunderstanding anything, and you can not be missing any evidence, whereas my approach requires humility, which says I must be misunderstanding something, or missing some evidence.
