Will you believe someone that your know from internet?

I knew him for 3 months. He is a kiwi and i am a Malaysian. We knew each other from internet. And we fall in love after some time. He told me how much he loves me and he told me all about his past. He was a playboy before, and he has kids with few women but all was just accident and he settled through law already. He told me all that before we started our relationship. He is not in touched with those women anymore. He came to Malaysia every year for business purpose and this year too. He scanned me his air ticket to show that he really will come. We supposed to be able to meet for the first time on 17th April but there was some accident happened and we couldn't meet. So we will just wait until September like our plan. He said he changed a lot for me, he is not a playboy now anymore, i am his only gf and he loves me so much and stuff. I can feel that he actually care about me. But i am not sure whether sometime i should trust him cos i will doubt for the things that i don't see. Anyway, we contact through internet almost everyday. He said he will come to Malaysia on September and gonna stay a month here and then he request me to go back with him. He will convinced my parents. I kind of doubt him sometimes and i think so much. Should i trust him?
