advice ??

so basically i’m a virgin and my boyfriend isn’t, i knew he wasn’t since the beginning of our relationship but recently i learned a lot about his past sex life from his friends. also learned that he lost his virginity in a bathroom at our “special place” and it just doesn’t feel special anymore... not to mention that i feel so intimidated by the girl it was with because of how good looking she is. i cried about it a lot but there’s nothing that can change what he did before he knew me... i just don’t know what to do, i told him how i feel and he said he’s sorry that i feel the way i do and that he just doesn’t regret doing any of it, this may seem dumb but i just have a weird feeling in my heart... any advice ???
