Help please, I am having issues showing emotion

How do I show my husband I care when I have no emotional range and can really only show anger and frustration

It also appears I am passing this on to my daughter and it is exacerbating my husbands own mental issues. He gets angry and sad and honestly I need to change me in order to show my daughter that it is ok to love her dad
My husband is 20 years older than me and has both a physical and mental disability. He thrives on physical affection. I am not that way I am afraid to share my emotions and tell him how I feel because in the past he has told me that I am "wrong" to feel that way. I am not one for physical touch and speaking about my emotions and usually when I am upset that is the only thing that comes through. I can express anger but can be very passive agressive about it. I get frustrated and talk under my breath. I want to be able to share my emotions with him and show him that I care because he does not trust me and as such my words don't hold much leverage
n addition to that I have tried traditional therapy but I do not communicate well verbally and it doesn't help. I have said I will try and do better and it works for a while but I always slip back into old habits and become aloof again.
Right now he is incredibly angry. Didn't talk to me on the phone when I called at lunch time and is just generally angry. I experience a great deal of stress when this occurs and as such draw further into myself trying to shield our daughter as well as myself by staying "hidden" and quiet and out of the way.

Amber, I find it a little strange that you and your husband got together in the first place. Love and affection as you have learned can be very important. Since the traditional therapy did not work you may want to seek a specialist that deals with that type of thing. You are right it would be better for your daughter to see affection and be able to display it as well.
Since I have always been able to display affection it is difficult for me to understand why you can not. I think human contact, affection, love, etc are important and healthy. Like I said before I think your best bet is to seek help from a therapist that deals with your behavior.
Good Luck
