His partner and kids live in Sweden, so one time when things "were complicated", he was in UK, got "matey" with Jayne, told her he was single, swapped some flirtatious text messages, got drunk one time, and kissed her.

Then he regretted it so came clean and told her he had a partner, but their relationship was complicated and....

that's it

Have I got it right?

Its Complicated lol

Yes you have.

But telling it like that will not be good enough for her to tell her story.

She needs to keep pretending something else went on.

Even though she has already told everyone that it didn't.

^ ^ ^ I see. How embarrassing, desperate, and attention seeking of her.
