Going to bed together…

So my bf and I of 2 years have lived together now for over a year. We’ve known each other for almost a decade and even dated in high school.

But besides that, the topic I’m really here to talk about: going to bed together.

So my bf has been staying up later than I do playing video games or watching YouTube or whatever, but here lately he doesn’t come to bed with me and this week specifically he’s slept on the couch until the wee hours of the morning when I’ve woken up to go to the bathroom or get water and I notice he isn’t there. It bothers me because I love going to bed together and cuddling before sleep but here lately it feels like I’m a burden or annoying if I ask. I just really don’t know what to do.

Should I talk to him and tell him that is makes me feel uncomfortable and like he’s being suspicious or hiding something from me?

Or am I over reacting and this is completely normal?
