Need to vent seeking opinions

Ok so we have been together almost 4 yrs. We haven't been on a date date in 3 yrs. We always do family stuff. I just feel we need to have time for ourselves. I told him this morning and he was like we don't have time because if our work schedules and we're parents. And i feel he's neglecting or relationship.He works during the week. I work weekends. And am a full time student during the week. He wanted to get a nanny so he can nap while i go to school. He works graveyard. I refused a nanny because i feel its a waste of money. Even though we can afford it.

I feel as if I'm single.

Am i wrong for feeling this way.😟😟😟

Our girls are 11mths and 2.5yr old. I also have a 13 and 10 yr old

What should i do?

I don't want to leave him.
