Hair advice

So I'm a natural brunette, with really dark brown hair. It looks almost black sometimes. This past year I've been dying it every shade of blonde and brown and I'm really torn. I love being blonde I thought I looked great (though I left my eyebrows alone) but it's so pricey and time consuming. But at the same time I don't want to go back to my natural color. Right now I'm sorta in a inbetween phase. Can I get some opinions? Should I go back to blonde? If so what shade? Or does dark hair suit me better? (Middle photo is my natural color and bottom is me right now) Thanks!
