B. used to is used:
1. To express a discontinued habit, i.e. to say that something regularly
happened in the past but no longer happens:
I used to play tennis a lot, but now I’m too lazy.
We used to live in a small village but now we live in London.
She didn’t use to like Tom but she quite likes him now.
2. To express a past routine. Here we are not making a contrast between
past and present. Very often there is a succession of actions. Here used
to is replaceable by would (but would cannot replace used to for a
discontinued habit as in B.1 above):
Tom and Ann were a young married couple. Every morning Tom
used to kiss (or would kiss) Ann and set off for work. Ann used to
stand (or would stand) at the window and wave goodbye.
Remember that used to has no present form. So for present habits or
routines we must use the simple present tense.

THE PAST CONTINUOUS TENSE

1. Form

The past continuous tense is formed by the past tense of the verb to be + the
present participle:
I was working I wasn’t working Were you working?

2. Main Uses of the Past Continuous Tense

A. We use the past continuous to say that someone was in the middle of doing
something at a certain time. The action or situation had already started before
this time but hadn’t finished.
Little Mary came in. She was eating an ice-cream cone.
This time last year I was living in Brazil.
The past continuous does not tell us whether an action was finished or not.
Perhaps it was finished, perhaps not.
Tom was cooking dinner. = He was in the middle of cooking the
dinner and we don’t know whether he finished cooking it.
Tom cooked the dinner. = He began and finished it.
