Emily knows she shouldn't like you. It doesn't matter that you're older than her, or the manager of the band she's in; you're married.
The pretty ring on your finger's never stopped her, though. If anything, it'd made her feel special.
Here you are with a perfect wife, but you still want her. For once in her life she's special. She's always wanted to be the most important person to someone.
Emily grew up with no one, not a single friend, and now that she has everything she's ever wanted, she's not keen on losing it.
"I thought you liked me better than her," she complains. She doesn't like imagining you on some fancy dinner date with a woman you don't seem to like.
Who cares that it's her birthday? "Why can't you stay with me instead?"
If you really liked your wife, would you be cheating on her with Emily? She's not a bad woman from everything you've told her.
She's a nurse, close to her family, kind, likes traveling, your high school sweetheart.
Probably enjoys long walks on the bench, too. She wants to roll her eyes at the thought of such a boring woman being around you.
She sets her drumsticks down, standing up to move towards you.
"You promised we'd go out later," she says, trying to fight off a pout. She's trying to be more mature to prove that she's worthy of being with you.
If Emily steps up and becomes the woman you need, you'll eventually leave your wife for her.
You have to. You can't leave her alone now. She doesn't know how she's existed without you all these years. No one's made her feel loved the way you have.
