Yes, exactly. If my husband has a problem with something I've done then he comes to me and bring it up and we discuss it. If I have a problem with something he's done, then it's the same but in reverse.
I would never complain about my husband to anyone else or talk about him behind his back and I would be really upset if he did that about me. We have been married ten years this month, very happily so, and it would NOT have lasted if he was going to his mom about our issues instead of me! What good does that do? It only makes things worse.
And then like OP I have "difficult" parents except I am not as nice about what I call people like that. I call a spade a spade so they're shit stirrers. They like drama and for the world to revolve around them and they don't like to see other people happy. They want to drag everyone down in misery like they are.
So, if I were to complain to my mom about my DH (back when I still talked to her... Or even my sister now, who I still talk to sometimes but not about anything like that because she is a lot like our mom in that way) then she would LOVE to hear my marriage wasn't going well and would try to take every opportunity to make it even worse.
(Not that she needed any extra opportunities. She already made backhanded compliments, divisive comments and tried to drive a wedge between any guy I'd ever dated and myself for my entire life.)
OP you should look into triangulation and direct communication. Don't talk to other people about things; go directly to the source. If the person is too unreasonable to talk to and work things out then you need to leave them.
I can't tell if your husband is awful or if you've tried to work things out with him or if you even like him or want to, because your post is so focused on your parents being mad and what THEY want.
You need to separate yourself from them and figure out what it is YOU want and do that. And don't talk to them about it because it sounds to me like they just want to drag you down despite acting like they're so nice and helpful.
If your husband just wants to drag you down too then talk to him and leave if it doesn't get better. You deserve better for yourself from your parents for sure. And if you feel you deserve better from your husband then you certainly do.
But all the power is in your hands. It all up to you. Do what is best for you and start living the life you truly want to live. Instead of talking to your mom, do you have any good friends? If not, try to make some. And also find a good therapist (not all of them are good). I have an amazing one who has helped me improve my life so much and I hope that you too can find the same. Best wishes.
