Phone records

Michelle

Husband and i started marriage counseling recently. We are separated but share a cellphone bill. We have verizon it is in his name. He is the account manager and i need to access the bill because i have a feeling he talks to other women and I don’t wanna keep putting my heart into our marriage if he is. Anyone know how i can access the online bill to see call and text logs?? I can’t do it without being acct manager... help?!!
