This question already has an answer here:
Recently my parents did matchmaking for me. After speaking with her, both the families and us have agreed on marriage.
However, I just came to learn from the bride-to-be that she had a relationship and she isn't a virgin. However, she told me it is already in her past.
Now it puts me in a great deal of dilemma. What does Islam say about that? I'm emotional at the moment but I want my religion to guide me through this to take the right decision. Please share your wisdom and proper references for my understanding.
