Her torment over ex's threesomes

MY girlfriend’s ex-husband has moved into a flat with two women.

- 

HAPPY THROUPLE: Her ex-fella has shacked up with two women and she's fuming.

They're all sleeping in one bed and openly telling the world they're a proud throuple.

My girlfriend is beside herself.

She is obsessed with his new setup and won't stop going on about it. She’s doing my head in.

She swears she’s no longer in love with him and wouldn't have him back if he crawled over broken glass, so why is she still waffling on about his “disgusting behaviour” and their old life together?

I hear her on the phone to his stepsister and a woman he used to work with. They gossip and pick over every aspect of his new life from who pays for what to who does what between the sheets.
