How should the financial split be handled in a love marriage?

Hi, So, me (26F) and my boyfriend (26M) are planning to tie the knot sometime early next year. We have been together for four years now and our parents recently met and things have been going smoothly for now. Both families like each other, and we agree on most things. We both come from upper middle class families and are looking for a sorta lavish Indian wedding? Nothing crazy or grand, but a beautiful wedding, maybe in Udaipur or some place near Rajasthan. Wouldn’t go as far to call it to a “big fat Indian wedding,” but you get the gist. Now, since our families have been meeting regularly, my parents want to a small Roka ceremony and invite our closest family members and friends. They want both set of extended families to meet and make things official. We aren’t planning a ring ceremony or such, so this event will be at a slightly larger scale (70-80 people), and next year in early Jan or something, we might do a pre-wedding reception to invite extended relatives and other acquaintances, and do a more intimate wedding with 150 people. So, my boyfriend and I are planning to split the wedding costs 50-50, and we were discussing how to split the Roka and the pre-wedding reception costs. He mentioned that typically it is hosted by the bride’s side of the family, and he said he isn’t interested in doing a pre-wedding reception since he isn’t that close to his extended family and him and his family have a smaller social circle than mine so he doesn’t want a host a pre-wedding reception. Now, my father is a retired government officer and my mother is a journalist, so they both have a huge network, and they would want to do a pre-wedding event to invite their friends and acquaintances. My parents are pretty open and chill, so they are not insisting on it, but it is the first wedding in my family since I am the oldest of all cousins, so I do want to respect their wishes and do it even if it is just a formality. Now I get that he isn’t interested in the reception, so maybe he shouldn’t be paying for it, but the Roka is something we should both be splitting, right? When I asked him why does he want my dad to pay for both these events in addition to the actual wedding, he said he isn’t interested in either of those events, and he is already spending a lot of money on my engagement ring and the honeymoon, so it isn’t a big deal. It didn’t exactly sit right with me, and I am having trouble processing how I should be feeling about this. What do you guys think the split should be and yes I understand sometimes people don’t want to follow traditions or engage in formalities, which is all fine, so I am not expecting him to pay for the reception because I respect his choice, but the Roka one didn’t sit right with me. Should I be offended at the fact that he wants my dad to pay for it and he’s throwing the whole “engagement ring” and “honeymoon expenses” in my face? What do you guys think?
