Want

So here we have a parent who feels she only has herself to blame for being 'so concerned and caring' after a failed attempt to emotionally manipulate her son into meeting her needs.
It is important to know that it is never a child's job to meet a parent's emotional needs and, unfortunately, that is the crux of a lot of child abuse or non-optimal parenting. These parents don't often know the difference between their wants and needs, don't know how to articulate either, and use manipulation as a way to coerce the other party into meeting those needs.
Imagine believing that it is your job to make your children happy. It isn't a far leap, conversely, to believe that it is your child's job to make you happy. And the logic of providing (or "giving in") everything to a child to make them happy then makes sense. But when you understand that it is not a parent's job to make children happy, but rather their job is to help the child become a healthy, functional, and independent adult - to facilitate the child's process of becoming whoever they are going to be, the result of which is happiness - then you can see how what made sense before is actually a detriment to the child. (And you can also see how it is see an active, and destructive, dynamic in that adult relationship.)
One thing I have noticed with abusive, or non-optimal parents, is their value on a result with no understanding of cause and effect. They force their children to smile a certain way in pictures because that's what children are supposed to do...without understanding that happiness for a child is a result, not a characteristic. They may beat their children because children should 'behave'...with no understanding of how children actually learn appropriate behavior. An adult parent might bemoan a child's lack of 'love' which, to that parent, means a certain frequency of calls, emails, gifts, food, or overt praise and emotional connection. Again, however, that is the result of a relationship, not the foundation of one.
It's similar to when women get upset that their significant others don't 'show their love enough'. Either they have different love languages, and aren't acknowledging how the other shows their love, or they don't realize that those gestures are the result of the relationship. (You know what? Guys do this too, though society usually associates it with an expectation of sex or sexual acts.) Coercing that behavior to make yourself feel loved will never work because in your heart you know those gestures weren't spontaneous.
A parent in a positional family ("because I'm your mother") may think they are 'entitled' to certain gestures because that is what children are 'supposed' to do without understanding the gestures are an effect. This parent likely did not do what they were 'supposed' to do, as we see in the example above, even if they had 'good intentions' because they didn't really understand the purpose of the parenting, and used the process, and manipulated their children, to meet their own emotional 'needs'.
