3...2...1 now fall in my arms now

I'm currently reading this book Sheer Mischief by Jill Mansell.
There's this part that I wna share cos I think it's really touching.

Bruno, fast asleep in the spare room, lay spread-eagled across the bed with one foot dangling over the side. Nina stood in the doorway and watched the man she had loved for the past ten years dream of the girl he loved.
Sadly, that girl wasn't herself. but she had done absolutely the right thing, Nina reassured herself. Breaking down and begging him to stay--maybe even attempting to bribe him with yet more money--would only have earned his contempt . Instead she had been cool, calm and understanding, and it was much the best way because now they could part as friends. More importantly, it kept the door open. Bruno would know he could always return.
You're leaving me now because you're besotted with someone called Maxine Vaughan, thought Nina, who is undoubtedly beautiful and who makes you laugh. She's probably brilliant in bed, too. But she can't possibly love you as much as I do, and that's why I'm letting you go. Because it doesnt matter how long it takes. I'm prepared to wait for you to come back.
