Ok, Deed, take care, ya. Too much negativity is not good, especially when it follows you? Dont/Wont want you to get into a depression... Try to let go of things in the office when you are going home, be happy and stay cheerful once you have knocked off? :)
As for your partner, I only have contempt for such people. I guess one step at a time for now, see how things go after the adjustment of job scope? I hope things will only improve for you. Jia you!
