We started talking 2 weeks ago. He professed his love quickly and planned to marry me. When he asked me to buy a phone prepaid card to call his daughter in London, it triggered me that this was a scam. Any stranger asking for money/gift online is definitely scamming you. He stopped talking to me when I refused to give him any. When I did the reverse image search on google, I found his photos on this site. That helped to confirm my suspicion.
