This is a very important advanced English topic as it could be counter-intuitive. Let’s talk about these expressions followed by the preposition to and the verb + ing:
Usually, ‘to’ makes up part of the infinitive or base form of the verb, for example, to walk, to sit, to go, to sing. – sometimes, ‘to’ is a preposition, and a preposition must be followed by a noun
‘ing’ is the gerund and is used to express a continuous action, for example, walking, sitting, going, singing. – the gerund is a word formed from a verb that acts as a noun
We can have expressions in English that use ‘to’ and ‘ing’ together, but only when ‘to’ is a preposition

Take care when ‘to’ is a particle of the infinitive of the verb: – I really wanted to going to the cinema yesterday. This sentence is incorrect because in this case, ‘to’ is not a preposition. We want to express the action we wanted to do yesterday, and we need to full infinitive of the verb.
– I really wanted to go to the cinema yesterday. This sentence is correct
