My parents found a match for me and we met each other and got engaged. My life immediately got better after we started talking to each other - I started offering salah 5 times (she does too). We call each other on Fajr to make sure we offer prayers on time. Everything was going great until I came to know about her past. She had relationship(s) in past and this hit me hard and I felt hurt due to that. I must admit that I am no saint and had a past too but I did repent couple of years before and never got into a relationship again, and always asked for forgiveness.
My question is - I did not go looking for a spouse but my parents did and I just agreed to their wish without asking many questions. I trusted Allah and still do, alhumdulillah. The thing is sometimes I get weird thoughts about her and her past and am scared about my future. I respect and trust her, and never ask her questions on her past. I know it's the present that matters but sometimes I get hurt whenever that topic comes up.
How do I build confidence within myself to accept how things are and forget the past? I am worried if she is the right person for me. I trust Allah for everything that HE does but just need some advice right now. I don't want to bug her by asking her question about her past because it might hurt her.
