Sorry but another "Que question". Please help....

Question

Hi my name is Teri and I am completely addicted to Spanish. I want to learn as much as possible. However there is one aspect in Spanish que me vuelve loca. It was harder than the subjunctive, impersonal and passive 'se' for me. That is 'que'. I know that it can mean that, what, which, whom and sometimes how (Qué tal?). But sometimes I see 'que' and I have no idea why it is there.

Could someone tell me from a grammatical perspective or any other reason why the following sentences contain 'que':

hemos de esperar, que todavía no es la hora -> we'll have to wait, as it isn't time yet.

Desde que te fuiste, nunca sido lo mismo -> Since you left, nothing been the same.

Por eso es que digo que las cosas no pasan como uno quiere -> Things dont happen the way one wants. (I think this is what it means)

Gracias Cuídate y un beso

Answer 1

Por eso es que digo que las cosas no pasan como uno quiere.

That's why I say that things do not go as you want.

or more directly

For that (reason) it is that I say things do not go as you want.

Note: In English we often omit a "that"

emos de esperar, que todavía no es la hora.

we'll have to wait, (since) or (as) it isn't time yet.

or

we'll have to wait, because it isn't time yet. or - it still isn't time.
