Anyone😢please

Me and my bf have been dating for almost 4 years now and this past week somthing has just seemed off he says he doesnt see it, we live 45 minutes away from eachother so we dont see eachother as much as we like but I’m freaking out like idk what to do.. I’m terrified Bc I love him and this is the worst feeling ever😢😢 it kills me to think of us as over I’m hoping we just need to see eachother.. has this happened to anyone? Idk what to do I literally feel sick right now
