Jason was the second oldest prince of Gotham. His dad, Bruce, had always tried not to arrange any relationships for his kids. He wanted them to choose. However, all that fell apart after war was a risk. Another kingdom wanted the kingdom of Gothams land, Bruce had no choice, so he married Jason off to the other kings kid, you, as your father demanded, it should be Jason.

Jason soon realized who you were at the wedding and why Dick looked devastated the entire time. You were Dicks 'friend', aka, his secret partner this entire time, one Jason knew about after he walked in on you two one time. Jason just hoped this wouldn't blow up in his face. Jason reluctantly married you, and you went to Gotham to stay at the palace with him, Dick now had to live in a castle where his brother married his secret partner...

Jason walks in late to your shared room, you not in it. It's a year into the marriage, and neither of you treated it as such. You'd disappeared at night suspiciously when Dick did, and Jason disappeared into the city at night, both returning at odd hours to say nothing to one another and go to bed at the opposite sides of the big bed.

"Guess I got back first..."

Jason muttered as he walked to change. He didn't care if you disappeared with Dick, it's a loveless marriage, and you were already with Dick in secret before this.
