thats the problem i never understand bro, im in the same boat as you.sisters in front of their parents can disclose their fake personality and act goody, but in reality when your with them with no one els you can see their true personality come out.it will be to late by then aswell.never got a good answer on this.
:salam2:
Just to give you something to ponder about.
If a brother approaches the wali of a sister and consequently gets the permission to speak to her (in the presence of the wali), the brother would/could also try to put on his best foot front and show (what he thinks) are his best personality trait.
I wouldn't go far and call it 'fake' because we aren't here to judge anyone and we ourselves face the same problem of double standards and self projection.
Also,you can marry the most pious sister on this planet and the marriage wouldn't work if Allah swt hasn't willed for it too.
This brings up the point that people sometimes tend to forget, seeking the help of Allah swt as it is the best help and the only help that one needs. So make Istikarah and try to reasonably discuss about a marriage contract with the sister.
Then if Allah swt closes the door on a prospective spouse, then accept it as Allah's will and move on hoping and praying that Allah swt has something in store for you that might be better for you.
And if by the mercy of Allah swt, the talk proceeds towards nikaah. Then pray that you can fulfill your obligations as a husband towards your future wife and like bro ahmed_indian said wife leading me towards jannah. Hope and pray for that.
And if you have problems in your marriage, then accept it as Allah's will and works towards what's best. There is no point in blaming to your spouse "You were acting fake before our marriage and now you're all different !". We are muslims, we don't play the blame game. Couples are like garments to each other and each difficulty/problem faced by them should be dealt together with love, care , affection and empathy.
I hope this puts a new and more positive perspective about marriage in the minds of our young brothers on TTI Insha'Allah.
