Rules in a relationship and broken rules.

The person I'd been seeing since February cheated on me on the day I saw the lawyer about my divorce stuff. I found out about it the next day after he posed a supposedly hypothetical question. We had talked about sleeping with other people, but only if the other was around when it happened. He made up these rules and didn't abide by them.

I'm not happy... feeling like trust has been broken.
