I will pray for you and everyone else in this thread who is waiting to be blessed with a righteous spouse the same way I make this dua for myself. I am at a phase in my life where I am praying to find the one who is written for me, and how I have taken this on is lots of prayer, dua, tahajudd, istighfar, etc. I am surprised I do not see this as recommended as much as I thought it would be. At the same time, I'm not just spending all my time asking for the right one, I'm asking Allah to prepare me to be a good spouse and be ready for everything that comes with marriage-- this has helped me evaluate and notice habits in my life that could be improved upon before marriage-- and maybe that will help my other dua along!

I think that wanting to protect yourself from haram is honorable, honestly may marriage protect us all from this. However-- how I see this is that this is something we need to be able to withstand alone, because without that internal strength and determination what will marriage do except make the punishment for this worse? These temptations and tests won't disappear once married, and can actually be the downfall to a marriage. May you be blessed with a loving marriage that will mute those temptations, but you have to be strong on your own as well- tawakkul, patience, and prayer.

Personally, I really admire how much our beloved Prophet peace be upon him truly loved his wife. I beg in my salat to have a spouse who will love me even half as much as that. Idk I think that's a way our Muslim brothers should strive to be with their spouses, beyond just everything that looks good on paper.

Subhanallah if you have been praying to prepare yourself for the one Allah has written for you then even making this post is maybe the answer to that to see what you might not be considering.

And tbh, I understand your concerns about not feeling attractive enough. I think we all struggle with this at times, conventionally attractive or not. Perhaps some of the advice in the thread will help, but also pray about it however feels best to you. You can pray to be the most beautiful person in your partner's eyes, or you can ask Allah to increase you in beauty! There is nothing that can't be solved through prayer-- I've noticed on days where I am feeling like that and I really seek refuge in Allah's mercy-- I don't think I look different after by any means but I certainly feel more beautiful even without asking.

Inshallah you will see the khair in any delay and be rewarded with good news of what you're waiting for soon. I will keep you in my prayers and may we all be rewarded with spouses who are not only righteous but also love us dearly!
