My ex boyfriend has a Tumblr account where you can ask him anonymous questions. I will admit that I've been looking at his Tumblr lately, though he doesn't know I have the link to it (he put the link on his dating profile though, and we met through the dating site so it's conceivable he could guess I've looked at it before when we were talking). Anyway, he makes a lot of posts asking people to ask him anonymous questions, and posts sample questions people could ask him. We broke up fairly amicably and he wanted to be friends (he broke up with me). I told him maybe someday, but I need to get to a good place emotionally. It's been over a month (we dated for 4 months), and I'm really curious about what he's thinking of me. I want to ask: "What would you say to and ask your most recent ex girlfriend if you could?"

My question is: is this creepy, stalker-y, or just a bad idea? Is it sort of dishonest since he wouldn't know it's me? Or is it okay since he always asks for questions and encourages people to do so? Would you ask your ex an anonymous question if you could?
