By my calculations, I'm gonna say by the 5th date (
which equals five weeks, because we went out every weekend).
How am I calculating by date #5? Well, we met on Match.com. His profile had about four pictures on it - two close-ups so you could see his face, and two longer shots where his face wasn't so clear, but you could see how tall he was, how he was built, etc. By date #3, he had taken down three of the four photos, only leaving up one of the long shots where you couldn't see his face. Now, he's not a big talker, and since we'd only been out a few times, I didn't want to grill him about it. So I asked several of my closer females - my sister, my co-worker who I shared a work space with, and my best friend - what they thought he was up to. They all agreed - he's being cautiously optimistic. He's slowly dismantling his profile as he sees how things are going. He leaves up one far away photo so other women can't really tell what he looks like, which discourages them from bothering to contact him, yet he's still technically leaving his profile up in case things don't work out with me.
By date #5, he'd very quietly taken down his profile completely, and I did the same. We never really discussed it with each other - when I saw him nixing his, I got rid of mine as well.
