I want to date someone like her, but not with this long term frustrating problem

I get frustrated when it takes Months for my partner to do specialty chores that should not take As long as it does. And I feel like I have to pester her about it the whole time or it might get forgotten and never happen. Even though she says she will do it and means it. And this builds up in me over time in multiple projects and it feels like I'm waiting and forced to even sort of numb myself a little sometimes to get through waiting. I ask her to do things for me so I can focus on other stuff, but then it doesn't work and I feel indeed to work double. But I don't want to not trust her to get things done. That's what would be a bad relationship.
