I can relate to this.
Some partners are supportive, some are indifferent, some are like yours.
What I realized about mine, was that she was a serial complainer well before she met me, just like I had a drinking problem before I met her.
We brought our own issues with us into the marriage.
When her number 1 issue for complaint was removed, my drinking, she was forced to find new ones.
Kinda like if they take your favorite drink off the market, it wouldn't stop you drinking, you just find a new one.
same / same.
So she started with I don't do enough, I don't earn enough, when am I going to ?? Whatever whatever.
It took about a year for her to realise she was still miserable and whiny and negative and she could no longer pin it all on me.
