is it haram to marry a non virgin girl who had an abortion before and was never married?
I am a virgin boy myself. the girl im with repents from the sin she did with her ex bf and is now a good muslim and prays five times a day. she is madly and deeply in love with me now and cares for me too much and respects me. I care about her too much and love her as well. and i want to marry her because of two reasons. first reason is since start she has been very honest with me and told me she is not a virgin and  had an abortion before 120 days and second reason is i love her too much.
I also think, if I back out i will never be able to forgive myself and i would think i am backing out because she was truthful and admitted her sin. If i back out from this girl and what if i marry a different girl and find out the different girl was not a virgin  after i get married to her?i would be devastated and might not be able to forgive myself  for getting rid of this girl i am with (the girl im with who had abortion from his ex bf).
Please let me know whether it is haram to marry her. I will do isthekhara.but please brother let me know whether it is haram in Islam to marry her and whther Al Quran says not to marry her.
