Do you ever feel useless?

My live in partner is a very hard working she was online selling pre loved clothes and she was also pregnant 2 months, while me im the one who delivers her sales during morning were both busy because I deliver and she will do household chores and in the evening I dont have much to do and in evening is the time where she is very busy, while im just scrolling on facebook and sharing her live, its not a big deal but Im the guy in this relationship, I should have more responsibilities than her right?
