Hi
pranava ... The way your partner stated her needs would've got my back up too. Something more along the lines of, "I know we're both stretched to the limit, but I'd love it if we could figure out ways to reconnect more often. I miss you!" would've been a LOT more helpful, I think. That might be a discussion for another day, when you're both rested and happy and sated.
As for how DP and I "renew the woo" ... we DTD often enough that both our needs are met. We set a date, and do it. It's agreed that if either of us aren't feeling totally into it, we mess around anyway, and guaranteed, we both end up having a great time.
On a day to day basis, she cooks, I clean, which balances the housework. She takes DD swimming on one of her mornings off so I can have some alone time, which makes me a happier person. She takes charge of DD in the evening so I can have a bath and read for an hour, which also makes me a much happier mama. For her, I take care of the household details, bills, appointments, etc, which is a load off her plate. I say all this, because it does help us have more space and time and energy to attend to each other.
We like hanging out with DD and are very attached to our bedtime nursing routine, so we haven't been on a true night out kind of date, but we do have "daytes" (daytime dates) where my mom or sister will look after DD and we'll go out for coffee and play bananagrams and a walk. Cheap and cheerful!
I encourage DP to take time for herself to recharge, and we both take responsibility for making sure we don't get to the end of our prospective ropes before doing something to recharge.
Take care, hon!
