ESTAFA Case - Legal Advice

Hi! I would like to know if I can file an estafa case. My ex bf asked me to send money to buy a car in the Philippines in May 2015. I send money for downpayment and monthly installments for 5-6 mos. We broke up because he has bad attitude. I mean really bad. He has no "utang na loob" and sending me nasty messages and curaing me if I will not send him money. Out of love I give in. But when I asked for financial help as my bro was in the hospital I never heard from him since then. Now he's in dubai and got a job last May 2016. I communicated and out of love and "katangahan" I tried my best for our relationship to work out. But his treating me like a "basura". I asked him to pay me but he said he did not owe me anything as I send the money to help him buy the car. I only have receipts of money transfers and text messages regarding our mutual agreement that I am also an owner of the car as we bought it as investment for our future and his nasty text messages to me abt sending money. Can I file a estafa case here in dubai or in manila? What are my chances? I want to get him a no departure order when he goes back home as I dont want him to get another victim here in UAE. Thanks
