Husband love me less cause im just only a mom

We’re married for 4 years already, and blessed with our little 3 year old son.

Everything was good and nice at the beginning, just these few months.

I feel like my husband started to less respect me, because i’m just only a mom, a house wive. While his sister works help her husband.

I can’t help my husband cause he’s too only employee. Her sister’s husban owns several store.

What should i do? I dont want him to stop loving me, i love my husband.
