My flirty friend crossed the line

I have a good friend, who I've known for nearly a decade and I value her friendship.

Dear Coleen

She has a great sense of humour and isn't the type to judge, plus she's always been kind and loyal.

The issue is, over the past 18 months she’s become incredibly flirty with my husband, usually when were on a night out with friends and alcohol is in the mix. He's the life and soul of every party, so he goes along with it for a laugh, but I absolutely know there's nothing more to it for him.

She does have a boyfriend, but it’s quite casual.
