First of all, I echo other people’s concerns about your safety. You need to make sure you’re away from any violence before you can contemplate getting over it. I hope you’re ok!
You probably have to trust your instincts in this case. If you feel fearful, then there must be a cause. Getting professional help seems like a no-brainer. People seek help for far less, and there’s no shame in it!
Whoever this person is, they’ve lost your trust – and rightfully so. Maybe it would help you to realize that even though they’ve lost your trust and possibly some of your respect, you can still love them as Jesus calls us to. But make sure it’s from a safe distance.
Of course I don’t know your situation, so this advice could be way off. Definitely go to a psychologist to help you recover. I’ll pray for you.
