Hi Haunted, I am sorry to read about your MIL, that women sounds like she has serious issues herself. You did well to keep your cool.
I am not able to give you any insight into replay, I did not care what stage my h was in, it didn't matter as it takes as long as it takes; there is no set time frame for a MLC unfortunately. I got on with my life and let him get on with his. Not much use to you, I am sorry. The vets are better at answering this kind of question.
Anyway, just wanted to say, keep moving onwards, you're doing great.
