@Maama,
Asalamu Alaikum va Rahmatullah,
Firstly, it is interesting for me to know whether you are a Shia or Sunni...
But regardless of your religion:
Love is beautiful without doubt, but do you really think that this is love?
In my opinion:
1- Ask your family and specially your parents what to do. They can help you better than anybody else.
2- Difference between religions is not something of minor importance specially if you are a practicing Muslim. So frankly speaking: Have you chosen the boy out of your mind and wise judgement or out of your emotions? A life which starts just out of emotions is capable of ending to divorce specially while you know that between we Muslims the divorce is strongly condemned.
So, I don't tell you that this is good or bad.
I just say that think about it more and more and try stay away from emotions.
