I have a friend [not so close]for a year , he is a muslim, we different in nationality, different religion, different culture. etc. and now, he plans to settle down and he proposed to me. The thing is before I have also a relationship with a muslim guy for more than a year and it didn't work out. Now am afraid if I accept again this proposal, I don't know if it will work out because of our differences. Is is fare for the second time that again I will take a chance of having a relationship with a foreigner? Please advise... as am really confused.I know I like this guy and maybe love also , the only thing withhold in me is his nationality and religion.
Please comment,, thanks.

If you have second thoughts, then no it is not right or the right time. How long have you know this person, how long have you been going out. What do you mean he intends to "settle down"

No, you should not accept his proposal as you have second thoughts... Moreover it is often seen that cultural differences do take a toll on relationships... If your not sure that you love him it would not be apt for you to settle down with him...

Is this friend the same guy as the one that is married with children?

No
