I was your DH 2 years ago. Been with my DH since we were teenagers now 30. I've had a really long history of depression and anxiety due to a tough upbringing and sexual abuse as a child.
The difference is, I've always taken meds for this.
We had 13 miscarriages and the last one broke me. I didn't want to be with him. Didn't want to be in our house. I didn't tell him but I pushed him away instead and then he left.
Once he left, I had a mental breakdown and ended up in a psychiatric hospital for 7 weeks.
It was only when I got intense therapy, help and a change of meds that I began to see clearly again.
I've put my wrongs right, we've been to marriage counselling, I don't push him away anymore, we have the best relationship we've ever had for the past year and I'm now 28 weeks pregnant.
I'm so sorry OP, I can't imagine how hard it is to be on the other side of it and especially pregnant and after miscarriages, I know that pain and I truly send all my love to you.
I'm not excusing his behaviour, but maybe this is a cry for help on the highest level and it involves you suffering which isn't fair.
If he won't get help, you have to walk for your own sanity, only when the depression fog lifted did I realise what a dogs life my DH had, his needs completely ignored, nobody to support him, you sound like you're in this position too.
You're more than welcome to private message me.
Sending love to you and all the luck in the world for your little one. Do what's right for you. You have to put yourself and baby first xxx
