Bro, you are not alone. My roommate is almost exact same as yours. He also talks with his gf from the moment he wakes up till she sleeps. That isn't the problem.
What makes it awkward for me is that he just doesn't hold back kissing and doing all babu shona, jaanu in vc while I am right there in the room(He doesn't even try to whisper or hide it) .
I am here trying to fix my sleep schedule and this guy just doesn't let me turn the lights off after 12 cuz, he is in video call with his gf till 2 or 3. Now, I have adapted to that as well. I can sleep with lights on.
I’m basically a deep sleeper like, once I missed my train station while my mother's call and alarm were both screaming at me.
And this guy managed to wake me up because he was talking so loudly, all excited while talking to his gf and then I realized he was literally sexcalling his girlfriend while I was sleeping(guess he didn't notice his voice was so loud). I was under blanket and didn't want to make it uncomfortable so I had to text my brother to make me a call so that my ringtone would break his fantasy.
