Nikaah & Marriage Issues

Q: What we know as Muslims that according to shariah man is responsible for the economic needs of his wife, but I have heard that economic responsibilities as per shariah do not include wife’s medical expenses. 

If such is the case, when in an Islamic family setup a woman is responsible to manage the house and look after her children she will have no time to earn her own income. Knowing about these circumstances when woman has no independent income because she has no employment as she was looking after the house which she is expected to do as a Muslim woman then why isn’t her husband obligated to finance her medical needs?

Q: Is it permissible for a husband to beat his wife? Men justify the beating by saying there is a hadith to say that hitting is permissible. If this hitting is not permissible, what will be the consequences in the akhirah?

Q: I wanted to marry a girl but later they told me that her mother breastfed me once when I was less than one year. I researched about it and according to my knowledge in Quran it is forbidden to marry but there is no evidence of how many times of breastfeeding is required. From hadith I found that there is one hadith from Hazrat Aaisha (radhiyallahu anha) which states that five breastfeeding is required to make it haram. Please guide me regarding this issue.
