re: Is it okay for a girl to give her boyfriend an ultimatum about proposing?

I was happy just being with her. (I'm pretty much on the level of a caveman) One day she said I like what we have and think we should get married. I said sure, you want me to surprise you with a proposal at some point. She said yeah, sure. The next day I proposed, she said that was unexpected, will be married 30 years next year.
