The quickest way to scare a man

My son is becoming the expert at scaring my sweetie. There are always new questions and saying.

"I love you"
"Mom are you marrying ****?"
"Mom is **** getting you a diamond ring?"
"**** we didnt always love you. When mommy was married to daddy we didnt."
"**** are you spending the night?"

I have to laugh at the expressions on my sweetie's face. Like a deer in the headlight look or maybe its one of complete fear. He never knows what exactly to say to my son when these questions arise.
