boyfriend lying

we been together for 2 years and 9 months. he's 26 years old and i'm 23. well when we met he said he was a virgin before he met me , he said that he never had sex with anyone BEFORE ME. well i think he's lying to me all this time because when we were going out in 2015 i slept over his parents house because he was living at his parents before we met still and he had condoms in his drawer 🙈maybe he bought them when we met or maybe he had them for other girls 😔 idk what's the truth but he says he was a virgin before he met me and never had sex but i don't believe him for some reason 😓i don't want to bring it up again because then we will get into an argument and fight over nothing so should i just move on and let it go ? or bring it up ? i just want to know if he was a virgin before he met me or not 😰 i told him i wasn't a virgin and he was okay with it idk i feel nervous feeling and think ima be sick 😷
