she has overdrawn our joint bank account more than once since she left. i noticed she has been getting netflix with that account. should i close that account?

i asked her to release me from our cell phone account so i could get my own plan but when i tried to do that she had a portion of the bill in collections so i payed the over due amount and the current bill.

i will go this weekend and see if its feesible to stay on the account and pay it or get my own and let her deal with loosing the phone.
