So I think the question is: If I were to tell my wife I didn't feel needed what would I mean?
That's easy for me to answer because I don't feel like my wife needs me right now but my answer may not be that of a typical man.
I will feel needed if my wife turns to me for emotional support. If I'm the rock she leans on when times are bad, if I'm the one she wants to share what's happening in her life when things are going well, that's when I'll feel needed.
The rest of it, buying her things, mowing the lawn, taking care of the house, I did all of that, but that's not being needed, that's just being a partner and carrying my share of the load, and maybe a little more than my share because I loved her. And I didn't mind doing it because I've always enjoyed doing stuff for her. Not long ago I changed the oil in her truck and took it for a drive to make sure nothing was wrong with it. I enjoyed doing that for her but she didn't need me to do it for her. She could have taken it to a garage. Now if she had wanted me to change the oil in her truck so she could hang out with me and keep me company while I was doing it like she used to do early in our relationship, I would have felt very needed.
My wife used to do a lot for me, too, and even though I didn't need her to do those things because I could have done them myself, I hope she felt appreciated. Not needed, but appreciated. I hope she felt needed not for what she did for me but for who she was to me.
I told you this was going to be different. I'm not sure I'm normal.
