I want my partner to work less
Do you think this is a good idea?
Her work conflicts with our plans a lot.
You cannot expect your partner's work to always fit into your schedule. If you have a problem with it, you should also be open to trying to make it work and not burden them.
I cannot deal with my life if my partner is working. If she don't spend enough time with me, I'll handle this by breaking up with her.
If she thinks she works too much, that's one thing. But if you just want her to be available to you at all times, that's an unreasonable expectation. You should have a talk with her about this issue and see if a compromise is possible.
