Feeling down because hubby wants to go see suicide squad with his friends and I can't go since I don't know anyone to watch my son :( we've been planning this for MONTHS and it sucks cause I can't go and I don't know when the next time will be for us to have a date night since I'm due soon. Feeling frustrated.
