Most Helpful Guy
I know when I tell my girlfriend that I love her I truly mean it, every time. She's been my best friend for a countless number of years, and all those years I was in denial that I liked her. So, now every time I say it I truly mean it. For those few times, where we're just messing around and trying to be cute, we use another phrase that's unique to us.
I mean it 100% of the time.
