I love one girl Angelina, but she just started dating. what should I do? we still like eachother.?

I once found this girl, Angelina on one of the friend profile, and I really liked that girl. Later I tried to add her on MySpace, but I was unable because, she had her profile set as privet. For a year I was trying and finally I was able to add her. It was the day when her mom died, at age 43. I was talking to her to make her fill better, than she gived me her number, and I started to talk to her on the phone. She is really beautiful, and her voice is amazing, I fell in love after I understood she is everything i always wanted. Every day we talked on the phone, everything were going perfect, we would almost fallow sleep while talking to each other, we both told each other that we like each other. Later she invited me to come to her city, its 3.5 hours away from mine. And we had amazing time. She said that she wanted me to see again. SO I was getting ready to come again maybe few days later. But something happened. I felt that she started ignoring me. And I was asking what’s wrong and she wouldn’t tell me. Then one day on the phone she told me she has a guy. And it was one of my (kind of) childhood friend. He is the biggest player in our town. I couldn’t say anything. So I offered her another date. And she agreed. So the next morning i came, and we had talk, I asked her why she did that to me, and asked her why she gived him a chance? And she couldn’t say anything. Then I we went on this once bridge and I told her that I loved her. And I told her sorry that I was late, and asked her to give me a chance. Just once chance. And she said to wait once week. She told me that I’m the most amazing guy but she can’t break up with him, but still asked me to wait one week. The guy is a total player, he had at list 10 girls in past, and she believe he would change for her. I believe he could. But that doesn’t make me believe that he will hurt her in future. For me she is everything and I am ready to give up everything. I love her, and I am ready to wait. Please let me know what should I do?
