My piano teacher was my teacher for 9 years of my life but the last time I seen her or talked to her was 3 years ago at my high school graduation. I feel like it would be weird to invite her to my wedding when last time she saw me was at my graduation and feel like I'm asking her for more gifts or money or something? Also that we have not seen each other. Idk but I also feel like I should invite her as she taught me for 9 years. Should I invite her or not or am I just over thinking this?
