factual or counter factual conditional?

[keannu]

I learned in a grammar book that conditionals are not affected by tense, but the following is confusing. Is it conditional1(factual conditional) to mean something that could possibly occur in the past or conditional2(counter-factual conditional) to mean something that can not possbily occur. Or does it depend?

-g.w
Mel- I thought if I opened myself up to him, that if I took a risk and told him my secret, it would show him how much I believed in him.

Another example would be like this.
He says "I would go if I were not ill"
=> He said that he would go if he were not ill.

Conditional 1 talks about events that may happen in the future.
Conditional 2 talks about imaginary present events (impossible) and future events that are unlikely to happen.

I asked which one it is....not the description of conditionals.
