Online bride... to be or not to be? I need advice.

I have been into these online dating sites for years already and I have also dated foreign guys. I am really into dating guys that are much older than me. Why? Because they are more mature and wiser than most of the guys of my age. And yes, I also have been dating an older foreign guy online for two years now. He recently just asked me to be marry him and I donít know if I should say yes or not. I am a bit confused as to becoming an online bride or not. I need advice on this.
