Lol! That's kinda what I did recently too. Him- "I love you" Me - "erm are you sure?" And we went on n on about it for a lil more while. I wasn't looking for reassurance. It's more like all kinds of mixed feelings and I only want to make sure if he actually is certain about what he feels before I feel/say something about it. And I don't think three months is too soon. Sometimes it can only take days and only you know and can define what you feel. Goodluck!
