Jake was still a grown man and able to make decisions for himself - he participated in the relationship willingly and as much as she did. Putting all the blame on Yaz is unfair imo, no smoke without fire.If you put yourself in his mums shoes it’s very easy to not like yaz, she rubbished his name on the internet as an abuser then went back to him and being partly the reason he was at that place at the wrong time which led to the accident, she probably wanted their toxic relationship to end months ago
