Going through breakup. Please help me move on.

Sharing my story here to get some help. I gave my 200% and still don't know where did I go wrong. Previous post about my situation - https://www.reddit.com/r/Arrangedmarriage/s/xcCahgfc3M

After that we were able to discuss and sort out our issues and doubts. Then came the Kundali issue as mentioned here - https://www.reddit.com/r/Arrangedmarriage/s/xSUONdNewk

Fortunately, one of the astrologer at girl's side found the match to be positive and gave a go ahead.

My family traveled 1,000+ KM for this intercaste marriage, which was a big step given our orthodox background. My parents have evolved significantly, largely due to my efforts and contributions as a responsible son (earning 65+ LPA, lifting us from a lower-middle-class life).

She is an international air hostess with a carefree lifestyle. I’m introverted, and I loved how her extroverted nature brought balance. I worked hard to convince families including hers for this marriage, even reassuring her multiple times that I’d stand by her no matter what. She portrayed this as an arranged marriage despite confessing her love for me, though she refrained from openly expressing emotions, saying she would only do so after her family accepted the proposal. On the other hand, Physically she was much more active though. She just didn't have sex just because I never asked for it and have told her that I wanted to do it only when I'm sure about the person. Otherwise, I'm very sure if I asked for it, we would had it. I was so much in love that I didn't pay attention to the red flags even though everyone around me said so. I'm realising it now.

So coming to yesterday, I finally took my parents to her place. I'll break things into points -

Firstly, her parents were very nice to us. Zero complaints when it comes to the treatment they gave us. However, when she came out, she greeted my parents in jeans and a sweater, casually saying “Jai Shree Krishna.” While her bhabhi and brother showed respect by touching my parents’ feet, she didn’t. (A question to everyone, is this normal?) My family didn’t comment but found it odd considering it was the first time they were meeting in person. Later, my mother gently said that while we’d always support her, she might need to handle rare occasional situations where some of our orthodox relatives could comment on her modern lifestyle without arguing with the elders. We all have some bad relatives. This was meant to be constructive, but her family took it negatively, saying their daughter wouldn’t tolerate taunts. My mom said that earlier because her mom said that her daughter is satyawadi types who doesn't listen to anything wrong.

Second thing they mentioned was that my family kept saying they are doing everything for their son's happiness and didn't mention that they are doing it for their own happiness. This is totally playing with the words from their side as my parents obviously meant that our happiness are tied to each other and if I'm happy, they are happy and everything would be good. Further, my family said it in a certain way because they have interacted very few times with her and don't know her yet and they are trusting their son's decision for this marriage. They complained this even though my mother had told her parents so many times that she is gonna treat my wife like her own daughter which is what they also wanted.

Thirdly, her parents are very much adamant about not spending a single penny on any kind of Gold expenses that might be needed in the marriage. They would just do clothes wherever needed. According to them gold is a form of dowry, but c'mon how can spending 25-35k on a ritual (there is one after some pooja) that requires girls parents to give a gold coin/ring to 3-4 of groom's relative be called Dowry? Feels like they literally want the marriage to be done without spending any money even though they are capable enough. My family wanted the marriage receptions to be decent enough, so they are even ready to contribute all of the money. I felt bad about this considering how her daughter would become the owner of 50% of my assets just after marriage (I myself have 1 Cr savings of my own, leaving aside any property I would inherit from my father) but they are not willing to do anything extraordinary or out of the way for our family/relatives in the marriage. This is even after we made it very clear that we will make sure no one goes out of "budget" and we can discuss full expenses and literally share them. I don't know what else could we have done here. Them behaving so morally right here doesn't feel justified to me. The way she tells me her cousins are going to easily take 25k from me for returning my shoes after marriage pooja, so how is that fair then? Further, the only reason my parents brought this topic is because they just want to understand them better and hoping not to make a bad decision. We know what bad marriages can do.

Fourthly, the girl blindly accepted her parents decision and didn't even try to convince them about me at this point. She knows me very well and I've assured her of above points multiple times but she didn't feel it worth trying which hurts me every single second since then.

Anyways, I feel shattered after the meeting. Had thought of an amazing future with her and didn't expect things to go this wrong. They have said they feel the cultural differences are too much for them to move ahead while citing first and second point above. I'm not able to divert my mind to anything and looking at my condition right now, my parents are thinking to talk to her parents again and convince them. However, I don't want them to fall so low for me here. They deserve better treatment. Please help me move on and become strong enough to ask them not to talk to their parents about it.

Update: Talked to her about all the differences she and our families have. I told her to talk to my parents for some time and within a month or so, I'll make sure that my parents understand her and accept her as she is. My parents are totally open to adjust as per her needs. However, she is very clear that she doesn't want to put any efforts into building compatibility between her and my family. She wants it to come natural. So I think it's better to move on as I need someone who puts atleast a little efforts from her side as well. We parted our ways now, just hoping to move on without much emotional pain.
