Welcome to the forum, UmightKnowme. Here is a place where you can feel some "virtual support", to supplement the lack of support you might get elsewhere. It's not quite the same as having loved ones around you, who can look you in the eye, and tell you that it's okay to feel the way you do, but it's a start.
When I read your post, I felt like I could have written it, myself. I have the exact same problem that you do. My DH is not supportive of my therapy. He tells me that it's all a bunch of shit, and I'm wasting my time. He hasn't done any research on PTSD, to try to understand what I'm going through. He can't understand why I can't put my past behind me, and focus on raising our family. He realizes that I have issues, but doesn't understand why I can't get passed them.
You mentioned that your counselors have spoken to him, my guy won't even consider speaking to a counselor. This, from a man who knows first-hand, the kind of family I came from, including a raving lunatic of a mother, and an alcoholic bastard of a stepfather, plus sexual abuse, emotional abuse, and neglect.
After 20 years together, he still gets upset with me, when I can't cope. There are constant issues about my inability to keep up with housework, laundry, etc. When I have "up" days, and am able to make progress, that progress is ignored. When I have "down" days, it never goes unnoticed.
I also feel like I have to hide my feelings. I cry silently, because he gets upset with me when I can't stop crying. When I really feel the need to yell and scream, I wait until everyone is sleeping, then I go out to the garage, sit in the car with the windows up, and cry, yell and scream until I get it all out. It leaves me exhausted, but vented.
Some have suggested that I leave my husband, but I do not feel that is an option. I love my husband, and though he does not understand what I'm going through, I know he loves me, too. It hurts him, to see me hurting, and I know he has difficulty dealing with that. When I try to talk about things that happened to me, he gets angry at those who hurt me. His anger does not comfort me. He comes from a family who does not share their feelings, so trying to change that is difficult for him. So, I keep it to myself. I try to make my therapy and healing as "low-key" as possible. He wants me to get better, but he has no faith in the medical industry.
I get no time to myself, to sort things out, that's why I've insisted on going to therapy. It gives me a little bit of time to think. Mind you, I am not at all happy with my therapist, right now, but that's a whole different issue. Though, DH would love it, if I never went back to her.
He doesn't want me to be depressed, but also doesn't want me to take antidepressants. He wants me to get over my traumas, but doesn't want me to discuss them. He wants me to be a loving, nurturing, supportive mother and wife, but does not realize that I'm numb and lost and I need support, too. It's a tangle of emotions and restraints and frustrations.
As for advice, I wish I had some, because I might try following it myself. I can tell you, for what it's worth, that YOU ARE NOT ALONE.
