So what if you are a hot blooded male.
She can always meet up with you with her hubby in tow. What are
you gonna do then ? A threesome ?
If her hubby ever finds out you have intentions to meet up with
her in a secret and dirty rendezvous, you better be careful he
don't bash your brains out and bury you in the outbacks.
She's just excited a friend is visiting, that happens to any
overseas singaporean.
Just go and visit as a friend, enjoy the place as a tourist.
The past is the past, there's a good reason why she didn't
married you in the first place.
