I would def. sep accounts and haver her pay her own bills while you split the cost of daycare.
tis was her choice and she needs to see what her choice means
so you split the past bills you pay for all the house bills, she pays for all her apartment bills she pays for her own cell phone and her own insurance (helath insurance should be different and you can keep your son and her on your insurance since you can't legally take her off yet)
