Yay Jen. Even a cheek kiss is a positive when it is initiated by the WA. Good stuff! And he did invite you to the club. I like how you are planning on feeling it out tomorrow.. and that you'll only actually go if he mentions it again. Shows you are in control.. that you aren't jumping on his every move.. so you're not pressuring or pursuing!
Keep up the good work!

PS. I think it's also a baby step when they come to the house a couple of times in the same day.. because for people that want their space it's got to be a good thing when they haven't gotten enough so they come back for more interaction!
