I have a Bolivian ram pair and I use that term loosely lol. The male spent 6 months keeping the female pinned to a small corner. I came home one day and they were in the middle of spawning. I think she just wasn't ready to spawn and it was him harassing her to spawn the whole time. Now that they have spawned once they each have a half of the tank and she stands up to him. It's pretty crazy how the dynamics work to be honest. Just make sure she has places to hide to break of line of sight and things should be OK.
