My fiance proposed to the wrong girl.

I(25f) met my fiance(27m) two years ago and we were supposed to get married next year. He proposed to me six months ago. I was so happy to say yes and was looking forward to settling down with him. He was everything I ever wanted and I truly love him.<br><br>Last weekend, I visited my friend and I found out that my fiance has a second social media account that I didn’t know about. I asked him over text and he told me that he doesn’t want his family to see his party pictures so I was okay with it. Then, Sunday night I found out he was in a different city. He told me he had work to do and needed to travel but it turned out he went to propose to the wrong woman. He proposed the wrong Gina. I was absolutely devastated. I broke down and cried after watching the video. He called me yesterday and apologized profusely and said he got cold feet and didn’t know what to do when I agreed to marry him. He said he can’t back out and didn’t know what to do so he asked his friend to pretend to be him and propose to the wrong girl so he can get out of the proposal. I was so mad and asked him if he really loved me or not. He said he did but he said I was the only woman he ever loved in his life and he said he panicked. He said he doesn’t want to lose me and begged me to stay with him. I asked if he wanted to marry me or not and he said no but he will do it anyway because he doesn’t want to lose me.<br><br>I don’t know if I can marry him. I was absolutely heartbroken. I love him very much but I don’t know if I can go on with marrying him. I was so excited to marry him but now I don’t know. I asked my best friend and she said I should dump him. Should I stay with him or leave him?
