Question

in infinitives where we use to and where we use it.

Answer 1

'used to + infinitive' and 'be/get usedto' People often get confused aboutthe use of used to + infinitive and be/get used to + 'ing' form because they look similar. They are, however, completely different. We use 'used to' to talk about things that happened inthe past – actions or states – that no longer happen now.
