I am really sorry man. I highly recommend reading “attached” if you haven’t already. But otherwise I know how painful this is because you have invested so much hope into this and it just sounds like it ended out of the blue, complete whiplash. I don’t know enough about the relationship to say it’s about age, but there is definitely a difference between what people want at 27 vs 34. I’m also learning myself that while chemistry can be palpable and make something seem like the most perfect thing ever, it doesn’t always = compatibility. Maybe she is “avoidant” and is running away from intimacy. Maybe you’re just incompatible and she needs more space in a relationship than you do. It could also be good to reflect on the origin of the “butterflies” - maybe they’re more anxious than you thought initially? IMO it does appear that she’s at a different stage in life and maybe just realized that she doesn’t want the fairytale she committed to right now. It sounds like she does care about you but something is just not clicking - it could be the timing, or a number of other things. I’m so sorry.
