Parents not happy with the girl one has married

Q: My parents are angry on me because I did not obey them and married one divorced lady. Actually they agreed initially but after some time my sisters made my mother refuse that girl but I was doing everything normally as I introduced that lady to mother and father by taking them to her home and cleared everything regarding her martial status. But my sisters forced my mother to reject her and I couldn't say no to my wife's family and had to get nikaah done in front of their family. I tried at least one year to make my family understand the situation and traveled from U.A.E to Pakistan twice to make my sisters understand. Now my question is that since I am married to that lady, my parents are not talking to me specially my mother but my father has no issue to meet me but he also does not contact me himself. Please advise me a dua as well so that I can get my parents back.

Income schemes

Q: When my father was alive he was on a good job but side by side he had an amount in regular income schemes from where he used to receive a certain amount monthly. Now as he has passed away, this amount from regular income scheme has remained the only way of earning. My question is that, in the case, is it permissible for me to go to my mother's house and eat there. I am happily married alhamdulillah.

Wearing a fake jacket

Q: A fake branded jacket came into my possession as a gift. I like the jacket, but I was informed it is a fake. Is it halaal for me to wear? I don't want to wear it because of the brand, but because it's comfortable. The brand logo is visible on the jacket stitched in.
