I take my babies to work with me every day. For some reason, they would rather sleep in my shirt than in their own bed. Since the female is so skittish, maybe you could try some tent time for her. It worked for my female and she was terrified of everything. Also, you could try putting their bonding pouch under your shirt throughout the day. Just go about your daily routine and this will allow them to get accustomed to your scent. If they can sleep with your scent, they will eventually associate you with safety. I don't know if you have tried using the scent pads yet, but you can use them when they're in their cage away from you. I usually put the scent pads under my bra for a day or so and put them in their pouch.
Also, if you can get some live mealies they will love you for it. They were my biggest bonding tool. Just give them some when they're with you, during tent time. I usually do one worm at a time. This way they have to interact with me to get more.
