Do I leave?

I’ve been with my partner for 5 years

He’s never treated me the way I’ve wanted to be treated, I’ve thought about leaving him periodically for the duration of our relationship, but I loved him

I got pregnant last year by accident, I thought about leaving multiple times during my pregnancy once I realised how much out of love I had fallen but hoped it would all work out once she arrived

I had my daughter 6 weeks ago and I am miserable. I love her more than life, but my partner and I do not get on. He hasn’t spoken a word to me in 3 days because I turned him down to have sex bang on 6 weeks. He loves his daughter, I see it completely. But the way he treats me and has always treated me has me up crying every night wanting better for my daughter and terrified of her growing up watching a dysfunctional relationship

It’s only been 6 weeks so I know I’ll be told to give it time, but having a daughter and reflecting back on how I get treated sometimes (days worth of silent treatment, bullied about weight, rude comments) I’ve just found that I want a better example for her.

I love my girl with all my heart, but if I had the option to go back to before I was pregnant and undo it, I would.

Is it okay to walk away with a newborn?
