There is no right or wrong answer. It is up to you to make this choice. It is up to you and you alone to say no or yes.
The question here is who do you want to be.
You may decide to continue and create a situation where some one else is dependent on you.It could spoil that person. Is that really kindness or cruelty. On the other hand are you giving favors so that you can get some thing back? If so you you might get disappointed and frustrated.
If it was up to me I would not want help to the point of spoiling my neighbor. I prefer to help those who need my help without expecting anything back from them.
This a a great opportunity to define yourself and stand your ground as who you chose to be.
