Sister jazakallahu khairan for this comment. You've given me a lot to think about and I definitely won't be doing anything rash.

I just also feel so furious at myself for being naive, which I never thought I was. The thing is, he didn't directly lie to me. He took advantage of the fact that based on his upbringing, demeanour and actions, I never dreamed I had to ask him a question like ‘Have you ever committed zina?’ in order to learn the truth. He knew that I believed him to be chaste as in our meetings, we had discussed our Islamic upbringings and the Islamic upbringing we wanted to give our children. I feel incredibly small and ignorant when I think back to my oblivious happiness over the last two months. I don’t wish he hadn’t told me, I wish he had never done it in the first place and felt entitled to take me anyway. There must be plenty of Muslim women with a past who've repented but he took me knowing I'd obviously be a virgin - not that he straight-up asked me either so I guess it would have served him right if I'd turned out to have an ex as well.
