What do you do for your birthday?

Do whatever your heart desires. Sounds like you have quite a variety of invitations. I would do the one that appeals to me the most. If it were me.. in your shoes.. I would sleep in, take a long hot bubbly tub bath. Meet my friends and just see where that takes you. Dont feel bad about not taking an offer from your x. Get a rain check and go another time with them.
