Engagement and Wedding

Base on the title, I don't know what to say.. That guy says that he already fill the form for marriage procedure but I still not sure about the proposal.. he says he want come to Malaysia in August for engagement ceremony.. Or else the engagement will be done in October.. What should I do.? I do I like his daughter coz she so cute and adorable.. but to marry person that i never know, it's so difficult choice and decision. Let say if I marry him, I need to guide him how to be a good muslim. I know he will do anything as long as I will be his wife... But I'm not enough knowledge about Islam and  still learning..

For Wedding , We not discuss yet coz he only say about engagement only... Hope the decision can help me to find a true love...
