There must be a rule I cannot get about ING, I explain. When somebody says ‘I’m looking forward to hearing from you’ where is the rule here that obliges you to put ING? The same with TO + verb + ING like to being. How come you have to + Ing? Is there an easy way to understand it?
The same regarding ‘you can try to help/helping’. I kind of understand it but I cannot explain it and that bugs me. Can someone give me something about ING to get rid of all the question marks right up in my mind?

In this kind of verb + verb situation, the ‘to’ is usually the infinitive particle:
I tried to help.
We wanted to go.
He liked to dance.
etc.
However, ‘look forward to’ is an idiomatic phrasal-prepositional verb, and ‘to’ is a preposition. Here are most of the phrasal-prepositional verbs with ‘to’:
I look forward to hearing from you.
I have to face up to meeting my ex-wife
We put our defeat down to batting so poorly.
I have to get down to studying soon.

Thank you! But what is the rule that applies when you say, for example " I have to go to my neighbour’s house to try helping him out setting up his TV" ?
Gerunds and infinitives can both be used as subjects, subject complements, and direct objects of verbs.
The choice between which to use as a direct object is sometimes dictated by the verb, leaving no choice. Which verbs can be followed by gerunds, which by infinitives, (and which by either) [size=150][color=red]must be memorized.[/size]
