So I feel like my boyfriend keeps so many secrets because he never tells me when he meets up with his baby mama and the day of his son graduation he never mentioned to me that his baby mama was going to be there .... Should I be worried ?! I do know that she is the mother but he still never told me or mentioned it to me I feel so betrayed because I tell him everything and don't keep secrets from me ...
