[subject] + be used to + [noun/verb-ing]
[subject] + get used to + [noun/verb-ing]
Be used to something means it is normal for you, so it isn't strange or difficult any more. Get used to something means it is slowly becoming normal.
Here to is a preposition, so it is followed by a noun, a pronoun or a verb with -ing, never the base verb.
Be shows the tense: am/is/are used to now, was/were used to in the past.
Get shows the process. It often goes with can't, will, getting and soon.
Used to + base verb (without be) is something different: a habit in the past that is finished now.
