Do you guys believe in bad gut feelings..? Like, have you ever had a bad gut feeling about something in your relationship and it turned out to be true?

My boyfriend has been on his phone A LOT more when we hang out together. He used to never be on his phone. And every time I look over he turns his phone away slightly? He also changed his notification setting so that it says “notification” instead of the actual message. Maybe I’m just overthinking it...
