I am a foreign fiancee and have been engaged to a Filipino lady for over a year. While waiting for the paperwork to be processed, I have been staying in the US. We were engaged in September 2012 and I have been back to see her three times. I have given her money to support her and her two children since we have been engaged with the understanding that we were to be married. I also paid for other items that she needed as per her requests. As is required to process her VISA she signed a notarized statement to her intentions to marry me. In April 2013 she meet an old acquaints and without my knowledge began a relationship with him. She went to great lengths to hide this relationship. It was during this time that her request for additional money began to occur. Her new boyfriend was aware of her engagement to me, and continued to pursue a relationship with her. In September 2013 an embassy number was given and she then decided to break off the engagement. At first she was unwilling to give me an answer as to why she was ending our relationship, but she finally confessed that she started seeing this other person in April and was more in love with him than me.
My question is, do I have legal recourse against her boyfriend for interfering with our relationship? Do I have recourse against her for all the support I gave with the understanding that she was to be my wife? Is this considered a Breach of Promise to Marry?
Thank you in advance.
