My GF told me I’m one in a million and that I’m the best boyfriend she’s ever had. I didn’t realize until later she said but BF. My heart shattered a little bit

About a month ago we were cuddling on the couch and I was being a good bf. I got her a cake, some flowers, I put together a playlist for her. I even put on some makeup. I was still in the process of putting on my makeup but I guess I put it on a little hot. I didn’t realize until she started licking my face but she said I was one in a million and that I’m the best boyfriend she’s ever had. She also told me she’s never met a man like me and that I’m the best. I got a little gassed up when she said it but later in the week I was thinking about it and I realized she said she’s never met a man like me. This caused a little rift in our relationship but I don’t think she ever noticed. I’m not very good at expressing myself to words so I didn’t say anything.
