if he had a thing with a girl at work
texted her
flirteed wiht her
brought her to your house and snogged her on your sofa while you were upstairs
then lied about it for months and said nothing had happened (despite being caught in the loo on the phone to this woman while on holiday claimed that he had not snogged her, that it was only a silly thing, even lied about that and tried to pretend it was someone else he was on the phone to, then you found out nearly a year later that was not true)
Would you think this was an affair?
Would you kick him out?
what would you do?
(name changing regular btw)
