I have a question pertaining to the following line in a manga.
The speaker just called his girlfriend by her first name, and this surprises someone. That person then asks about it, and the speaker is explaining it to that person.
What confuses me is the て form ending the sentence. What would be the difference between 「なって」 and 「なった」 here?
I am fairly confident that this is not a request or command. If something is being omitted, I am not sure what it could be.
There have been other circumstances, though never in formal written material. In conversation, are sentences perhaps occasionally ended in the て form out of carelessness?
I would appreciate any help understanding this.
