Who Will She Choose?, chapter 1

Billie and Adrienne had been happily married for some time, or so Billie thought. Secretly Adrienne had been seeing Mike. When ever Billie was with the boys Adie would sneak out and go to Mikes place.

One day Adie was driving over to Mike's place, when she got to the door she noticed a note in Mike's handwriting.

Dearest Adie,
I've planned a special treat for you, meet me at Blue Lagoon restaurant, tell the waiter that you're with me and he will lead you over.

With all my heart
Mike

Adie jumped back in her car and drove over to Blue Lagoon restaurant as quickly as she could. She arrived and walked up to the waiter,
"Hi, I'm here with Mike Dirnt."
"Oh right. Right this way Miss."
He led her over to a big table, and surly Mike was waiting there for her. "Hey there Beautiful." Mike said standing up.
"Hi Mike, I can't stay long coz Billie is at home with the boys and he will be getting worried."
Suddenly her phone started ringing. She picked it up, looked at the screen, it was Billie. "Hello," she said.
"Adie! God! Where are you?! The boys and I have been looking all over the house! We've been worried sick!"
"It's ok Billie, I'm on at the shops, coz we needed some bread and milk."
"Ok Adie."
Suddenly Mike hugged Adie and he started laughing. "Who's there with you Adie?"
"Oh. Its Mike, I saw him here and we were having a chat. Well Billie you know where I am. Bye."
"Love you Adie."
"I know Billie, I know."

She turned off her phone and looked at Mike, tears filling her eyes. "What's up Babe?" Mike asked.
"I dunno if I can keep doing this. Secretly seeing you behind Billie's back," Adie replied.
"Who do you love most?"
"I don't know. I have to go" She picked up her stuff and left.

What will she do now?
