We've been together 4 and a half years. We have 3 year old DS. Things have been hard for a while now, I struggle with my MH in general (I think he does too) and he's had a long-term issue with his back which he's uncomfortable with pretty much 24/7 and that has made him hate his life and makes things more difficult when he's in constant pain, can't sleep, has to work long hours etc.
We've come close to splitting up a couple of times in the last year (always him wanting to leave, sick of his life, wants to rot alone etc.) I try to support him as much as I can (im a SAHM to our son and im with him 24/7, I have no outside help. He's an easy child but it is still wearing) but his physical issue hasn't improved despite him seeing a chiropractor fairly regularly, after exhausting other options like GP and physio. I feel like this is the main problem here. Before he was suffering with his back he was really active and physically fit but he's deteriorated in the last few years, which I know bothers him as he's lost muscle mass and strength.
Anyway, a bit off-topic sorry, things weren't great over Xmas and I felt like I was treading on eggshells and feeling nervous about us because things have been difficult for a while. Things came to a head last night and we had an almighty row. And have barely spoken since. I've tried asking him to make up and talk and start to work things out but he's not interested. I wrote him a letter today pouring my heart out about how much I love him and how devastated I am and basically begging him to stay, but he's opened it (No idea if he read it or not) and just left it on the side. I feel like a fucking mug!! I put my feelings down in writing because if I attempt to talk about this face-to-face I end up a snivelling mess and I don't want that infront of our son!! When I'm crying and emotional infront of him he doesn't comfort me at all and is adamant that "there's nothing to say" etc.
Today has been hell. I've been stuck in the house with him and our son, my heart absolutely broken and trying but failing to hide my tears. He's shown me no affection or comfort, it's like I'm not even there. When I was crying in the kitchen tonight he came in and said things like "do you think I want this" "I'm hurting too" I mean I could've gone for him, he's not the one who's been sobbing on and off for 24 hours or begging their partner and embarrassing themselves.
I know he loves me, he tells me so, but he says he's doesn't want a relationship anymore, he doesn't want to be around anyone anymore - not just me. I'm on my fucking knees right now. We've not got a pot to piss in, our house is council (in my name), he's got nowhere he can go unless he borrows money and goes back to family 600 miles away, plus I have no job or childcare! We struggle as it is and he's on good money. It's making me sick with grief and rage overthinking that he's here only because there's no where else and I can't carry on like that if he serious of leaving!
This whole post is a massive mess and I probably haven't explained it very eloquently, but it's late and my whole body is aching and I don't have anyone else to turn to for advice. So I'm hoping one of you can help me!
