Myself and DH went through a stage, it was a horrible, horrible time.
I couldn't see any point in having him around, he had really let me down and I didn't think I could see a way forward.
What I would do, in your position is say to him how you feel. It sounds like you are suffering from postnatal depression.
You haven't felt like yourself since having your DD, so in some respects, he may be right, there may be a tone to your voice that he's picking up on. Maybe you are bone tired and are struggling with the emotional and mental changes that have happened since becoming a mother. If we're all honest, most of us struggle.
How did we get back to some sense of normality?
I think we both needed to be really open with each other. We spoke about how I make him feel, and how he makes me feel.
We discussed that we needed to be more open to being clear about our emotional, mental and physical needs. Before this it was like we were in a physical one man upmanship of who was struggling the most with feeling crap, and that was building resentment. We've got back to the point where we are recognising each others needs and putting them first sometimes.
We've also discussed that we have started to fall into a bit of a coparenting rut, we've forgotten our relationship. Or even what we like about each other.
Once a week, we try to have a nice time as a couple, maybe watching half a film before bed. We send each other a few videos from tiktok or Instagram every few days, generally try to have some semblance of a relationship outside of our child.
Also, if we're really struggling I boil it down to, you are the other parent of my children.
I trust no one with them more than you, I see you parent our kids, and I see kindness, I see vulnerability, I see a person who is committed enough to them, that you'd die for them. Even if that is the only reason I can find to love and respect you, its because of those values our children will grow up feeling loved... and we work from there.
He has had times where he's expressed that every time he struggles with me, all he has to do is look at how I am with our kids, he knows he could never see me as bad, when he's seen the softness that our children bring out in me.
It isn't always easy, but he needs to work with you, and being a present partner...and to really appreciate how motherhood has changed you.
We undergo massive changes in pregnancy and the first few years, and actually if your partner realises these, how could he ever see you as bad?
