Seeking Peace After a Mistake

Assalamu alaikum everyone. There's this sister I know who had a man in her life who promised marriage... but instead he encouraged her to commit major sins, including zina. She carries heavy regret for it every single day, and worries deeply that she'll never find the righteous husband meant for her who can accept her past. She has sincerely repented, stopped the wrongdoing, and now prays constantly for Allah's forgiveness. But she still feels it's not enough, and her biggest anxiety is that she'll be alone and unwanted by potential suitors. Today, she wears hijab, prays regularly, and honestly this whole experience has drawn her closer to her deen. What do you think? Can she ever find inner peace and a good, understanding nasib who will marry her and build a halal family together?
