BABY FEVER!!

I want a baby so bad... it's driving me crazy. All of my friends are getting married and having babies and I just want that so bad. I have been with my boyfriend for a year and a half and he has a 2 year old from his last relationship so I know he probably isn't ready to have another kid, plus I would like to at least be engaged but.... he won't ask the question and I'm trying not to get ahead of myself but it's just bothering me.
