I'm scared af

I'm a first-year CSE student...

and I started dating this guy in my first semester. Everything’s been really nice, but the thing is i completely messed up my exams.

There were so many times when I’d sit down to study, but my mind would just keep looping back to him. , before I knew it, the end sem was here. I tried studying and everything! but nothing was making sense.

Meanwhile, my boyfriend studied well and I could’ve asked him for help but I didn’t want him to find out how dumb I was. Now, he literally topped the exams, and I’m on the verge of getting a backlog.

I know this might sound naive, but I don’t want to tell him about it. I just don’t want him to think I didn’t study or feel sad because of me. Also, his friend (who’s a girl) got great marks, and I’m not even good at a single thing, while he’s really good at almost everything. I don’t want him to have the slightest doubt or worry that I can’t even secure passing marks.

I just don’t want to tell anyone except my parents. Is it okay to lie to him and just not tell him?
