"They are jealous and don't want to talk to each other anymore."
Translation:Ils sont jaloux et ne veulent plus se parler.
FYI, there are a lot of ne ... X words! You can use ne ... jamais (never), ne ... rien (nothing) and yet more. It's a good idea to make a list, and each time you come up against a new one, add it!
I should have thought through my note-taking better before starting it. If it were a language totally new to me I'd have an excuse, but I did French at school (a long time ago!) so I should have known better. I've been listing things like colours, ways to tell the time, directions, faire ... X phrases/verbs, etc. When I've completed the course my aim is to go through the notebooks and list everything I should have been doing from the start! There will be quite a few negatives, as it were! Good luck :)
