Money Issue

Dear Sir, My husband was engaged(engagement) with a girl till 2015 and was working in Dubai till then. They were in a relation for 4years. He used to send her gifts like phone iPad dresses etc from Dubai. Also I found a few receipts of funds deposited in the girls acc which is of total 1lac 20thousand. He lost his job in 2014 and was in search of new job that's when the girl started acting weird and broke the engagement with him stating that he lied to her abt he losing his job and now he can't fulfil her needs as the amount he earns is less than what she spends in 2 week's. There are whatsapp chat record supporting this. After which in 2016 we had an arrange marriage. It's very recently I found about the money that was given to her with the receipt and the chats. It's clear that she has used him till he had job in Dubai and dumped him later. I confronted her brother about this and the girl too. And I asked to return all the money that she has used while they were engaged. But they are denying to gv it back. Can a case be filed for cheating and breach of trust? And with all d proof we have supporting the transfer in her account is the money recoverable?
