ENJOY YOUR PARTY!!!!!!!!!!!!! Sounds like so much fun! and well deserved... for you and the little one!
I know it is extremely hard w/o him there but soak up all of the wonderful people who have chosen to be there and celebrate life with you. your H will most likely be miserable today... and to his own doing. Wonder what is going through his mind... better yet don't! think of all the wonderful baby goodies you will recieve today and soon have all over your place waiting for the baby to come home and play with.
I'm sending you all of my positive energies! enjoy your day as best as you can... it is normal to have a range of emotions... just always remember to pick yourself up... as my mom tells me every day... no one can pick you up by you... and when you do you will feel better about yourself!
