Feeling of falling out of love

My boyfriend and I have been together for a little over a year and we’re both 17. I was completely and madly in love with him up until today. I don’t know what it is, it could just be the day but I felt as though I was falling out of love with him. I don’t even know how that could be possible though because he never did anything wrong and I was so in love with him just yesterday. We did just spend a few days apart due to busy schedules which is unusual for us but we saw each other again for a few hours today. Do y’all think this could be me actually falling out of love with my boyfriend? Because it hurts me thinking that may be the case.
