My girlfriend doesn’t love me. Should I confront her about it or just let it go?

I feel like my girlfriend doesn’t love me anymore. We had an amazing start, but recently things have changed. She’s distant, distracted, and when I express how I feel, she accuses me of being controlling or uncaring. She even told me she doesn't know why she loves me. Why is this happening, and should I confront her about it?
