Nikaah & Marriage Issues

Q: My question is it permissible to have nikah with girl with whose mother I did zina? Now the story is that I did zina with a woman but the reality is that the woman did zina with me because I was 14 and she had three daughters at that time. Now my family did my nikah with her older daughter, she loves me and I love her and we happy for one another. I already did tawbah for what I did and I ask for forgiveness from Allah Almighty. Now we are in relationship already in nikah but I have a question sometimes in my mind, so is it allowed in Islam that her daughter be my lawful wife or I have to leave her? The zina one time we did almost 12 years passed, after that I never tried to do that with her mother nor her mother tried with me. Kindly answer me with details and references.

Q: My wife is two weeks pregnant and Alhumdulillah we already have 3 kids. We live in Canada and here the situation is very different. She is only one who takes care of the kids and home and she also does a job. We are very confused because our younger daughter is nine months old and the middle boy is 2 years old and the elder is 4 years old. Now my wife feels that she is not strong and we didn't even think to have another baby yet. Because we already have so much responsibilities and she said she cannot handle it right now. So is it possible that she abort it because the soul is not there now just a fluid is there. We are very scared because we cannot and don't want to make Allah angry with us.

Q: Girl's choice in marriage is final though violating other family and status equality as given in fiqh of marriage. Allah orders children not to cause grievous hurt to the heart of parents. Allah says, he does not delay punishment to such children in this very world. So how can such marriages be happy? Is not the marriage with the approval of both the girl and her parents more meritorious and rewarding? And are parents entitled to say to the girl that if she's bent upon her own choice, she should do it without parents taking any part in it as they aren't accepting her choice?
