Sir please tell me is it true or not please

They can not marry by their religion if you live in a county operated by Islamic law. So by the church rules it is not accepted. If your countries rules allows it, then you will just have to leave your family and have no contact with them, as they will not accept this.

Thus the end for many love marriages in other places for other reasons. You have to chose parents or husband.
