Don't think like this - "I help out around the house as much as I can". If you operate like this you are subconsciously dumping the whole domestic load on her. Which comes with generations of conditioning.
Then for her 'the home' its like living in a summer of persistent rain with a few days of sunshine. It is still a grey, gloomy summer for her. You drive 50% of the activity so discharge at least the same amount. Work as a team it is much easier to do that today, tomorrow and in the long run.
There is enough information on this site already if you look, which gives you the same answer. Nothing stirs a woman up more than a man with his shirt sleeves rolled up, halfway between his wrist and his elbow, (but no more apparently) hands deep in the sink scrubbing the last sticky Weetabix spots from their DD's breakfast bowl, or helping her draw a tree in wax crayon (and loving the moment), or emptying the bin and putting a new liner inside while also checking when to buy the next roll, and marking it on the shopping list......while knowing that this is what life is and still loving it.
Work together. Be romantic.
Get up at 06:00 on a weekend day when you are together. Make and pack a picnic. Pack the car and put the kids spare clothes, a rug and some toys in the boot. Make her a cup of tea and lay the breakfast table. When you have all eaten, let her shower and get dressed while you wash up and clear the table. Dress the kids. Pack the dinosaur and the dog. Drive to the country or the seaside and spend a day together. Look at nature, stones (no phones), trees, bees, butterflies, grasses, wild flowers and marvel together.
Rub her feet. Ask for a hug. Kiss her cheek with no agenda. Love unconditionally.
See what happens.
