It hadn't always been this way, and if Arthur had to argue the fact he would be sure to remind her of just that: it hadn't always been the way it was now.
In fact, in the beginning, Molly didn't trust Arthur as far as she could throw him. What really got his goat about that is none other than one simple fact: he had done absolutely nothing for her not to trust him! They barely spoke, they had only one class together since Molly was so far advanced, and she didn't act like she really liked him so why would she ever bother to find a reason not to trust him?
Arthur shook his head and freed his thoughts as he reached out his hand to take hers. He had been listening to her go on and on for hours now, and the window in which visitors were allowed was closing soon.
"Honey."
At the sound of his voice she immediately snapped her lips shut and turned to face him, realizing that she had been staring into space and using vivid hand motions to tell her lengthy story about the time they tried to soak the Headmaster with the alcoholic drinks they shouldn't have even brought on campus.
"Yes?"
"It's almost time to go." He spoke this as quickly and quietly as possible, knowing he would have to be gentle with her. She would be upset that she had to leave soon. He knew that she wanted nothing more than to be by his side and that it hurt her to be away for long.
"Arthur-"
"-Molly, I promise I'll be fine."
Every night was the same thing. The same type of visit; the same time of phone calls...The worry filled ones. The ones in which she could not sleep or did not want to leave. He understood because he would be the exact same way with her/ In fact, he was- with every single one of their childrens' births. But this was different. He had just been through extensive surgery to patch together the wounds of his snake bite and the surgery, (although heavily medicated with various spells and potions), had taken a toll out of him. It was time for her to rest, just as it was time for him.
And as always, her heart clung to the only words she needed to hear from him- his pleading; soft commanding- "Trust me."
And as always, she did.
With a quick kiss to the forehead, she smoothed back his stray, red hairs and smiled strongly for him.
"I have always trusted you, Arthur."
"No you haven't." He replied cheekily; not missing a beat.
"That is an argument for another day." She mumbled softly, grabbing her coat and turning on her heel to exit the room.
She was a pain in his neck sometimes, but their love and trust was enough to cover that and make it worth the while. It always did.
