AIO for being hurt my girlfriend doesn’t care about my graduation?

In a few days I'm gonna graduate with my BSN. I don't want a big celebration at all but It's still a big accomplishment for me. I get she wants to think about it all realistically, and we talked about that when she got home. But, I feel bad now. i've always congratulated her for her own achievements, and even though we'll still be stretched for time, still be parents, etc. this is a big step in both of our lives.
