Whether i should get married to her or not?

I am an 30 years old male Indian. I had 3 relationship in the past out of which i went physical with only one. I met a girl on the internet on 7th Oct 2010. She is a 32 years old brazilian. At the beginning she told me about her life. She said she is a divorcee and has a 9 years old kid. She got married at the age of 19 and got divorced the next years. She told me she had another relationship with a man for 4 years. 5 months down the line. I chatted with her friend and she gave me some hints about her past. I was worried about her past since we decided to get married. Everyday i started asking her about her past. Finally she said after divorce she kissed lot of men in the parties but did not have sex with them. It sounded weired to me. She kissed but not had sex...i think it is impossible to control sexual urge after kissing. Till today she says she never had sex with strangers. I went on asking more. She declared another relationship which never lasted long but she slept with that guy also.....Guys i have no idea why she was hiding these things from me. I made her explain that i love her and will forgive her for her deeds in the past. I know she loves me but the biggest problem is she lies and she hides.....It has been 6 months that we are on the internet and decided to get married. After knowing that she lies and hides i am confused whether i should get married to her or not.....I don even know how many men she has slept with....infact ido not know how many men have ****** her!!! sorry for the language....i am frustrated!!! I need a girl who never hides or lies to me and love me a lot. She loves me but i do not know if she is telling the truth!!! Please help me decide whether i should get married to her or no!!!
