:salam2: Dear sister,
Only Allah sobhanaho knows the best and inshallah will help you with this problem.
I will advice you with the following:
1. If you accepted to be a good Muslim wife then he should directly ask you to marry him. Otherwise you should leave back to your country ASAP.
2. In any case, you should tell your family about your full address and contact information and the information about the man and his family in details.
3.Marriage needs good intention from both sides and it is not enough to be from one side only.
You need both neutral wise Muslim people to be between you, not from his family or friends.
4.I don't think you should spend a long time thinking, it is a one day decision.
5. If you decided to marry, be sure to make it in the court and registered in the Embassy.
6. You are a single woman in a strange country, YOU SHOULD THINK SERIOUSLY ABOUT YOUR SAFETY.
One of the reasons that makes the man angry in the Muslim countries is that, the society, sometimes, have problems accepting converting western women because of their history (relations) before Islam. Thats why the converting men/women should try to forget that part and keep it between them and Allah Sobhanaho. It is a problem in the man's soul.
Inshallah everything will be fine with you.
