Please separate them. I had two rescue beardies that I got just last June - a male, Gonzo, and a female, Evee. They had been housed together by their previous owners and poor Evee got the brunt of it. She had a fractured, infected jaw, scars on her neck from Gonzo constantly trying to get her. She was malnourished (emaciated really) and dehydrated. Gonzo actually ended up being the first of the two to pass in August, and I just lost my Evee in February. I tried desperately to help both.
The cheapest, most efficient, and healthiest option is to separate them. It is in their best interest absolutely. If you want to read up on what can happen, just look at my old post on Gonzo and Evee (which included a $500 jaw surgery to remove the infection and she was to have another jaw surgery if she had lived). It sounds like you love them, and everyone knows their own beardies better than a stranger on the internet, but it sounds like your female is being put through the ringer and it is not good for her
