Reg cancellation of wedding

I'm 32M, We were engaged during of April 2021. Engagemnt happened in the Party hall with all our closed relatives presence, we ve taken many photos and videos. Marriage was planned on Sept month first week, Both families were proceeding further with wedding activities and almost completed everything. Myself and girl had good understanding for past 3-4 month. I have informed friends,family and neighbors about the wedding and everyone are prepared as well. On 27th July , in the casual call in which below points are also discussed 1. Before engagement girls father asked me where to send the furniture either to home town or chennai (where myself n girl works) i was planning to buy furniture and other stuff for our home , I asked about furniture because I didn't want both families to buy the same furniture , It would be a lot , thats what my intention was, I didn't ask about furniture because I wanted it , I myself wanted to buy it myself. 2. In our religion girl family will take care of the wedding, I came to know from the girl that they are gonna spend 17 lakhs for the wedding, Due to this covid situation only few people will be able to attend the wedding , so we thought spending 17 lakhs for the wedding is not very necessary , so we asked to spend less , save the rest for girls's future purposes, not that we are't interested in the grand wedding .. we just thought covid situation makes it less necessary . 3. We didn't ask or demand anything since the beginning , v jus asked abt the gold so that V could answer our relatives and we also wanted to know how much they are expecting from us incase of any. I'm the only son for my parents , all that belongs to me is for girl only , we wasn't expecting anything from them. Very next day, girl's father informed that they are going to cancel the wedding saying that they are not interested in proceeding further. after hearing this my father became so upset, he had heart issue, We kept him in observation for next 4 days. He apologized to girls father for all this and explained them that our intentions werent money oriented. I met girls parents in person and apologized as well. we asked their availability to sit and talk about this and sort rectify this misunderstanding together. but it seems they have already decided and informing us My father who was already sick and mentally down due to this current situation, prepared and travelled to chennai and met girls parents with my relatives. situation doesn't seem to be improving, Girl's father prepared mutual agreement for wedding cancellation and asking us to sign which we haven't signed yet. We have no intention in cancelling the wedding. My father said that he will sign any agreement for making this wedding happen but not to cancel. Usually if the groom's family cancels wedding then there will a huge show with threats of criminal action against all. Kindly suggest
