He loves you a lot, to sit there with you. He feels helpless, and will supply what you need. He is very caring.
Men like to solve things. They (in my experience) don't like to have to guess our needs. When I am asked how he may help, I tell him. Or I tell him even before he asks.
"Honey, today I am feeling scared for no reason, could you not worry about me and just be your regular happy self, I will tell you if I need something different".
"Sweet, I need a hug, and I don't know why"!
"Do not ask me how I am today, I am angry for no reason and I don't want to latch onto something I am not upset about and cause some problems".
That is how we both treat each other. We are up front honest, and direct. We fill each others needs. Sometimes I am repressing and do not know how to get to my emotions, and he digs around in me until I am upset and hollering or crying defeatedly and he responds correctly. He doesn't take it personally when I am picking fights (usually) and comforts me when I tell him I need it (usually). My husband isn't overly affectionate, and I like that. He is a rock in my churning sea, and I appreciate his attempts - and when he fubs it, I clarify.
Whenever I have good days, I am extra nice. I am usually nice nearly every day. I laugh at his jokes, and listen to his boring science facts. I comment back about the height of the lawn, and give him space when he needs it.
Our idea is, if we each try to make the other happy - we will both be happy in each other.
If you don't know how to answer him, tell him. "My emotions are so confused, I don't even know what I want. Thank you for caring. <3's "
It sounds like he really does want to help your world be a happier, healthier place, and that is a great thing.
