I could buy her everything and she was happy

Thanks! So I am only allowed to use "was/were" when it is a coditional clause?

For example: "If you were good, we could do that"

I'm sure that's not the case.

Thank you, me too, this is why I am asking. Is there a certain rule or clue?
At one time i read somehting like: "I was interested in your offer". So I thought I could use it like I did in my first sentence.

No certain rule, no. Mixed conditionals can be used in some circumstances.

hmm, ok, thank you. there are sill a lot of questions marks left, but their does not seem to be a solution to my problem....
