Every-time I say something positive in work, like I'm going on holiday - she'll say ugh I don't like insert holiday destination. Or, if I'm going to get a pet, she doesn't like pets or if I went out to eat, she'll say that she doesn't like food like that.
It's really starting to grate on me.
If I'm busy then she's always busier
.
I've tried being friendly but the relationship never goes any further. She's a total cow.
