I'm sorry that he hurt you. I have a similar situation as you so you are not alone in this.
I'm not sure legally what qualifies as abuse and not. But personally I think whatever you are forced into should count as abuse. If you didn't want to speak up because you feared for your safety, then yes I think it is abuse. But that is my opinion which doesn't count for anything.
((Hugs)) I hope you can find the answers you are looking for. And if you need my feel free to send me a message
