Assalamu Alaikum - Dealing with trauma and thoughts about marriage

Assalamu Alaikum, I’m using different wording but speaking from the same place as your post. I’m a Muslim man in my early twenties, working and trying my best to follow Islam - praying, avoiding Haram, and living a halal lifestyle. Lately my parents keep asking when I’ll get married, but I’ve lost the desire because of a traumatic thing that happened in college. I was very close with a teacher who one day comforted me after I found out my childhood cat had died. She took me to a private room to let me cry and then gave me a drink and some tablets she said were paracetamol. I felt dizzy soon after and she led me into a classroom, locked the door saying I could sleep, and then took advantage of me sexually. It was non-consensual; I was drugged and assaulted. A male teacher later told me to go home and that the police might come. At home my parents asked questions but I didn’t tell them what happened because I felt ashamed. The next day the woman accused me of assaulting her, and many people didn’t believe my side. She asked the college to drop the complaint, and then near the end of the year she privately admitted to another teacher that she had assaulted me, but by then nothing could be done - she would deny it to the police and the opportunity for justice had gone. This was three years ago. Since then I’ve felt violated, sick, and deeply ashamed. I’ve kept to my faith - never smoked, never drank, eat halal, pray - but I used to want to save myself for my future wife and that feels gone now. I avoid sexual talk or touch and I don’t want to marry. I’m asking: would it be wrong in Islam to refuse marriage because of this? How do I cope in a way that’s Islamic - should I accept this as a trial from Allah (SWT)? And if I ever do choose to marry, do I have an obligation to tell my future spouse about what happened? JazakAllah khair for reading. I’d appreciate kind, sincere advice from brothers who understand trauma and Islamic rulings, and practical steps for healing while staying faithful.
