I am wondering how to form a statement using would (le conditionnel?) from a past perspective. As in "I spent a lot of time deciding what I would eat for lunch today". Could someone tell me if the below is correct? Apologies for the spelling/accent errors as I am typing on a computer where i don't know how to type those, but i've tried to approximate the critical ones below.
j'ai passe' beaucoup de temps `a decider quoi je mangerais pour dejeuner aujourd'hui.
maybe i should say "quoi j'allais manger pour..."?
