This sounds blown out of proportion to me. What an adult chooses to do with thier free time is thier business. I can understand why she felt that way but if it's enough to drive a nail instead of spark a conversation there was turbulence before this. For your next relationship be upfront with your interests and set healthy boundaries with your partner. Anyone who throws out the "you fucked up the best thing that ever happened to you" isn't really a person you want in your life. That speaks loudly about what kind of person she is.

Stop beating yourself up, learn from this and move on.

Healthy boundaries-stay the fuck out of my phone. Trusting/loving adults don't need to do that. That's what proper communication is for.
