The talk about other girls

So me and my boyfriend were talking... I told him I am glad that he was my first everything.. My first boyfriend, first time to have sex.... He told be he felt very guilty that I waited for someone special and he didn't.... He told he sleep with 6 other girls and one of them he has a daughter with... I told it is okay with me . It happens... But he keeps apologize to me and that he said that he didn't wait for me... How can I tell that I am okay with it? That things happen...
