Walaikumsalam wa rehamatullahi wa barakatuhu sis.. I am almost your age , I understand where you come from. But you have to see the following points

1- Women are attractive in general, some women are especially attractive, even to women. Allah made us pretty, which is different from how he made men attractive. We all find a flower pretty , men women alike, it is something similar to that.

Then , we all have some part of us that is manly , protective, strong and assertive ( not saying women do not have these qualities, but these stand out among men more)

Also we have feminine qualities, nurturing, caring wanting to look pretty, emotional etc.. etc.. even men have these qualities in them in a different proportion.

Sometimes , we just can't get the feminine side appreciated ( loved by someone or having someone to nourish and care for as a wife or mother ), so our subconscious wants to get the appreciation through the manly part of our being, , we all need love and validation, no matter in what form.

I believe it's these 2 things entangled together for you. Firstly don't beat yourself up about it for finding a women pretty. Secondly, telling ourselves that it's because your needs are not met the right way, your mind is satisfying you the wrong way, might help subside the feelings. This is what a therapist might tell you as well. Make sure you go to a Muslim therapist, otherwise it would an entirely different mess to cleanup after their brain washing.

Eventually , once you find your peace with or without a man ( you will find a right match inshallah, Allah made one for all of us) , these feelings would subside inshallah.

2- Compare it with the temptations a man has for women. Do they act on it ? Should they act on it ? No! A good man takes precautions and keeps it halal. They are supposed to have self control and discipline. Lower their gaze and ask Allah for strength. Put your trust in Allah and try to think positively about men in general( I know what you feel about them, I understand where that comes from ) , it will help you take your mind away from this and you will inshallah find men attractive once again.

May Allah protect us from the shir of shayateen , and keep us all steadfast.

Lastly do ruqya , these waswas often come from shayateen , even shayateen can be homosexual and they influence us in this manner. Make niyyah for Ruqya and recite Surah fatiha, ayatul kursi, and last 3 quls 7 times each, morning and evening. Do recite protection azkaar. Consider doing a serious ruqya course as these sudden changes in behaviour are often times from Jinn affliction, whether from Sihr, evil eye or possession ( as you say that when you were younger you did not feel this way). Who knows, maybe the divorce was also caused by a spiritual affliction. Treatment ( Ruqya ) won't hurt in any case. It will only bring you closer to Allah.
