Is he lying ?

So my bf has been rlly hrny lately which is strange to me because before he wouldn’t really want to do much. Today he came over and I was on his phone using his Snapchat to view stories of a party he was at last night and he got mad and said I’m always “doing this” which is literally a lie because I hardly ever grab or use his phone lol. So I said “always?🙄 I hardly ever use your phone” and he got mad and said he wanted to go home I immediately knew his mood changed but didn’t think much of it. He said he had to go home cause he was tired and wanted to sleep but when we walked outside he said oh I’m going to my friends house rn to hang out so I said ok? Then why did you lie and say you were tired and going home? He proceeded to get mad and blame it on me ? Lol

Something felt a bit off w him getting so defensive so I calmly asked him “are you hiding something from me?” He got so mad he started fidgeting walking all over the place crying saying no!!! Are you stupid??? You’re stressing me out!! So I said “all I did was ask a question?” He walked away angry and left . Is he hiding something? Help me out pls!
