People usually don’t notice the things you do for them until you stop doing those things. 

I preach all the time that in order to be successful, you need to provide value and to help others. Many times, those people forget that you do all those nice things for them and after a while they “expect” it. As soon as you pull back then you receive an email or text saying, “What the fuck?” Be careful of other’s who try and take advantage of you and never really realize the value you provide to them.
