She asks for help with things, gets frustrated (sometimes she'll raise her voice) when I ask for more details to clarify what she needs, then blames me when she doesn't explain what she needs and I do things "the wrong way"

for a while now most of the time we spend together is when she needs something (said she didn't have enough time [but she did for friends], now she's unemployed, going to school part time and nothing else, still "doesn't have time")

So I pretty much stopped helping her with shit and she gets upset when I refuse (because it's draining to be asked for help, offer help, and then be treated like shit because I can't guess what exactly she wants)

We've been together almost 6 years and it's been like this about a year

I'm asking for advice on communication specifically though, not on this issue

Because things were great for 5 years prior to this and maybe I could do something differently to improve things
