am i overreacting?

So i recently downloaded snapchat and i noticed that my husband already had a snapchat account (but he doesnt have snapchat on his phone). so i asked him if he had snapchat and he said that I must of created it for him (which i didnt). He maintained that he never had snapchat and that he had no idea how he could possibly have an account. i was totally confused. So after a few days I said to him to download it so that I can send him pictures and stuff. so he downloads it and logged in (eventually). And on it he had two like chats i guess (I dont really know dnapchat properly lol). they were just with two guys that he used to work with so im not that bothered. I dont know how to see his friends but his snapchat score (?) was like 7 so he obviously hasnt really used it. Im just totally confused why he would pretend he didnt have it when he clearly did. He is a totally convincing liar like he can pull the wool over my eyes so easily which kinda makes me suspicious. Anyway, so I dont think hes like cheating on me or anything, but it just annoys me that he wasnt honest. Like it makes me think he was hiding something in the past. What do you guys think? Am I totally overreacting?
