I get what you are saying.
You should really verbalize your feelings with your family and aquaintances instead of editing your feelings.
With the men in your life, have you ever asked what he'll bring to the table?
Even if what he brings to the relationship is obvious to you.
Just to see that he is actually thinking about what he can do for you too might be of comfort.
Hopefully the "parasites" are thinking about how to please you, but just suck at verbalizing. Ha.
If not, you've practically told him that you want, too. And that you expect some give with the take.
