<human>: Can you provide a brief overview of the text?

So I little bit of background... This friend and I were dating for around a month then she got a new job that demanded more time to be invested into it so we both took the decision to end our dating relationship there and then but we agreed that we could still use a physical one purely for sexual enjoyment. All was fine and I would go round to her a couple of nights a week and she would come round to mine. She recently got pretty drunk out with her friends and she asked if she could come round to mine and I said she couldn't because I have to be up early in the morning. She then starts flipping out and telling me how she's slept with other men. I'm not bothered by this because I know that what we have is just sex. I then go on to tell her this and she asks if I've slept with other women and I have so I tell her so. She flips out more and breaks down into tears and says she feels sick at the thought of me being with other women.

How is this rational when she is sleeping with other men but when I sleep with other women, I'm the bad guy? She's now wanting to end our sexual relationship all-together which isn't what I would like and I know it's not what she wants due to how well we get on together.

Is this threat and attempt to get back at me for doing something perfectly fine but something that she sees as wrong?

I'm so damn confused.
<bot>: Ex and I have a casual sexual relationship but she doesn't want me sleeping with anyone else even though she feels she can.
