so is it better to get a boy from a open not so strict family or rather a boy from the same type of harsh strict up bringing
Any mother who purposely brought up her children in a strict environment would never ask this question. In her mind that is the proper upbringing and also, she wouldn’t consider it strict. She would think it’s normal.
And if you didn’t have a say in how your daughter was brought up, then why would you have a say in who she marries?
Was she brought up elsewhere, and now she lives with you? It is usually better to marry a likeminded person. If you have think that maybe it would indeed be better for her for marry someone who is not so strict, you should be discussing that with your daughter, not with strangers on an anonymous forum.
Maybe you did bring her up and had a say and now regret how strict you brought her up? If she’s ready for marriage, it’s probably too late to change that.
