John James met on Match.com..went to lagos, Nigeria sent him $2000 western union has child sarah Internet

I met this man on Match.Com and e mailed for 2 weeks. Thought it was a good match. He claimed to make $150,000 owned his own construction co., then got an e amil that he had a big job in Lagos, Nigeria. Emailed and called cell said he lost his credit card. He was forced to pay for motel...then needed money for food for his daughter. Then when he went to come home, through KLM airlines sent itinerary so I could pick him up. Then called to say he was detained by airport police (I did hear a LOT OF common noise in background). Since I never met him, demanded to talk w/daughter. He claims to be widowed, lost wife&son in auto accident. Know he told autgoriies that I was his 'wife' so daughter called ME "mom". I have sent over $2,500 in Western Union. He sent ticket confirmation through KLM Air. I called, it was canceled due to "no-show". He called next day... was in hotel. Then asked for another $200 to change flights, them KLM said he never paid, which he did tell me..said he was going to pay upon arrival.  I am out of everything I have.... no money, no credit, etc. Desperately need help !!!!!!!
