I'm sorry you felt that way after your first session.

It's awful that your husband said that in the moment. Hopefully the fact that he went with you lets you know that deep down, he realizes he plays a role in the problems too. My husband also has a way of putting it all on me when he's frustrated. It isn't fair, but it's a defense mechanism.
My husband and I go to counseling every week or every other week. He didn't want to go at first, but just the fact of him going meant a lot to me. Lately he's saying we can't afford it, so we'll see...
Some days we walk out of counseling and i feel worse than I did before, other times we (I) feel better at the end of a session. I understand your frustration and worry, I feel it too.
I also know that my husband has deep-seated reasons for his hostility, that are worth his time to investigate. But it's emotional work and that's uncomfortable for him, so he resists.
What I try to remember is that when my husband displays anger or hostility, thee's really another emotion underneath; every negative or uncomfortable emotion comes across as anger, because he may not realize or be in touch with what is truly under it. Anger is easier and safer and more self-protective; he feels he needs to show it. Believe me, in his hostile, self-defensive moments, it is hard for me to remember that with compassion--like last night, for example. I certainly wasn't the "bigger person" when I wanted him to be less angry. I was a needy person. And it made things worse. It doesn't mean I'm "wrong" for having my own emotional needs, it just means if he's feeling something negative/uncomfortable, he won't be able to help me feel better. So in those moments, I need to learn to just be patient until he's ready to be the happy, loving husband I know. I'm still learning to apply this in the tough moments.
Even if it takes two to cause or solve a problem, it can help strengthen you to focus on your own behaviors through individual counseling or otherwise--that's what I'm trying to do in my own marriage. Sometimes my "self-work" helps us, and other times I can't draw on my well of strength--like last night. But I'm going to keep making deposits into my strength bank, and I hope you do too.
I hope you and your husband continued to go to counseling, or you've been going on your own--either way I hope things are getting better for you.
