Here is some background: both my parents have given me and my sister so much freedom considering that we are from a traditional muslim background. We've been allowed to have boyfriends and pretty much do whatever we want (within reason ofc). Although there has never been any force put on us to marry a muslim, both my parents have always said to us both, that once we go to uni, they would like for us to find someone to marry from a muslim background, even if they are not religious themselves. There has never been any other rules - my parents could not care less about race ect. This rule is because my extended family is VERY religious and traditional so if we do not marry from a muslim background, it will break my family apart, and both of my parents will lose their relationship with their siblings and parents.
Although not ideal, I have always understood this rule as simply trying to respect my grandparents and wider family, and plan on folllowing it when I go to university next year myself. However my sister is in her first year of uni now, and has gotten herself a new boyfriend, who is from a traditional Christian background. This has caused my parents so much upset, as they said they feel like they have failed by being too liberal with us, and are constantly crying and arguing with my sister over this. I have tried to talk to my sister, and explain it from their side, as she is only a week into this relationship with this boy and I dont want her to cause herself unneccesary pain if it goes on further. However my sister refuses to listen, and what's worse, has come home with love bites from him, which has caused even more upset in my house.
I really hate having to talk to my sister like this, and I hate that my parents are ranting to me about it constantly. I also feel so much resentment towards my sister - I feel that the rule is simply in place so that our parents dont have to lose their family, and my sister is being selfish by ignoring it blatantly. I'm not trying to say that in her first year of university she needs to find her husband lol, all I'm saying is that I dont think she should get into a relationship which is never gonna work out, and is just causing my parents so much upset.
Am I wrong? I honestly dont know what to do. Nothing that anyone has said to my sister has helped. I feel like I've tried everything. Please advise
