Seeking Guidance on a Personal Struggle

As-salamu alaykum everyone, I'm reaching out here feeling lost and unsure of where to turn, as this is a sensitive matter and I need sincere advice. I'm a Muslim woman raised in a strict, loving family whom I deeply respect-I don't interact with non-mahram men, I've never dated, I dress modestly, pray five times daily, and attend Islamic lectures. However, I've been grappling with a personal challenge for about two years after hearing friends discuss their relationships in ways that aren't aligned with our faith. I know it's wrong, and I constantly make dua, begging Allah to help me overcome this habit, but it feels incredibly difficult and I worry I won't be able to stop. I'm also terrified it might impact my future marriage, fearing that if my potential husband finds out, he might not want to marry me. I understand we're all human and make mistakes, and I'm committed to changing, but I need practical advice and support because I'm really hard on myself about this every day. Jazakum Allahu khayran for any understanding and help.
