Since it was rape, the intercourse that happened was not your choice. It was force, like a torture. The other thing is that since you didn’t enjoy it, you didn’t experience pleasure. So, you have not broken the root vow.

To break the vow, the goal should be pleasure and one should have the experience of that pleasure. That would complete the goal and break the root vow.

There is detailed information available that defines what a total loss of root vows entails. Also, according my divinations, it would be better for you to live in ordination than not.
