I know "have to" expresses 'obligations to do something' and I know how to use it in the sentences. For example:
People have to leave their rural areas.
But I have seen ‘having to’ being used as gerunds and in the present continuous tense. For example:
Having read them all, I came to think the first and second sentence are in the present continuous tense.
I'm not sure but my opinion about these three sentences are as follows:
First sentence means:
- people are obliged to leave their rural areas (The obligation of leaving rural areas is continuing in present and they are now leaving their areas)
The second sentence means:
- She is in the obligation of looking after herself now. (she didn't have to look after before but now she is in the obligation to look after herself)
I think the third sentence is not in present continuous tense.
"Love means never having to say you're sorry"
- It means: Love means you never have to say you're sorry.
Here Having to replaces you have to
Am I correct in my opinion? Please correct me If I'm wrong about the meanings of those sentences.
I think one more example could be:
Employment means you have to work
Employment means having to work.
Again, here having to replaces you have to. Do both of these sentences convey the same meaning?
