Is it the end?

Me and my so have been together for quite sometime and we used to thing we were forever. But lately it doesn’t feel that way anymore… is it the end? He still says i am the love of his life but everything seems soo meaningless nowadays… For instance, today we were supposed to go to the movies in the afternoon since we haven’t seem each other since Wednesday, but he said he couldn’t make it bc he’s going skating in the afternoon but we can go tonight. He’s not cheating on me or anything, he actually goes skating every weekend with 3 friends and he always shows me videos of them there and he’s also not the cheating tipe. Anyway, a few months ago he wouldn’t just cancel on me like that, he would just leave skate for the following weekend. Little things like that have changed and i just don’t feel like our relationship is his priority anymore… We have already talked about this and he has apologized and said i am his number one priority, but every week something like that happens and invalidates his words… Is is the end of us? Or how can i fix it? I love him so much and I believe that he loves me too
