I'm jealous of his past.

First I want to say I recognize the past is in the past. It's done. It's over. But my boyfriend is older and lived in California most of his life while I have lived in a small, sheltered town in the north that he just recently moved to. He has told me great stories about partying, threesomes, and just flat out fun things he has done in Cali. He told me he went to Burning Man and of course that's where people, definitely chicks walk around naked and party at night and it gets to me that he experienced that. Whenever Burning Man is brought up I get lowkey enraged. He says it was the best experience of his life and goes into this loving trance talking about it and even talking about California he says he misses those days so much, the drugs, the concerts, the sexy girls, etc. He always says how it's so boring living here. I feel like I will never be his favorite memory. I feel boring. Like he's settling for me now that he's here. And nothing will compare to his past experiences and he would rather be there than here with me. I said we should take a trip to California and he said no if he went he would never come back. And he will randomly say "one day I'm gonna pack my bags and move back to Cali" and I say "without me?" And he goes "oh yeah. You too." Like wow, thanks. 😒 We live together and are planning a future together but when he says that I'm like... mmk. and he doesn't even say that to be funny. At first I was interested in hearing about those experiences and had a honest "good for you" attitude about it but now I can't help but be bitter about it. He talks about it a LOT, kind of brags sometimes, and it makes me feel like shit.
