I dont know what to do
I'm having a lot of conflicts with my boyfriend because of a story he thinks happened to me in the past with me and another guy. I'm a virgin and never had a boyfriend before him. He doesn't believe that and thinks that sexual stuff happened between me and another guy before and I told him no no no it's not true , i have never had interaction with the guy. My boyfriend doesnt believe that tho and a few months ago he said if you dont tell me that something happened between you and that guy im going to leave. So of course i freak out , lie and just tell him i had sexual interaction with the guy because i thought if i say that hes just gonna take that in and never bring it up again . Which was wrong of me . Later , he wanted to talk about the situation and i said "no no i lied , i'm sorry. dont believe what i said, I was just scared for you to leave " . So from then on he had that in his mind. last week , we texted the boy and he also denied it of course . a few days later my boyfriend woke up and said that he dont believe me and he know that something happened between me and the guy and i was denying it but then he was saying again im leaving if u dont tell me the truth and i was telling him that nothing happened and after some time i really started panicking and i just said fine i had something with him so he could stop bothering me with the situation and i just said i texted the boy and told him to deny it. ( my mind work really bad when im nervous or in panic ) Now today he says we're going to talk about what happened and I dont know what to do because i have nothing to say because it never happened and i'm so scared . Before i went to sleep yesterday , he told me if i cant tell him something i never told him about , and i dont explain the whole situation to him Hes going to leave forever and of course I dont have nothing i can say .. I'm so lost and sad and scared . I dont know.
