I started reading this thread as I'm in the very early stages of dating someone who's autistic, and I thought it might be helpful. But, I've had to stop several times in tears about how so many of you are describing my marriage to my ex-husband, the feeling ignored/unseen, being so lonely, having to mediate between him and the DC, always taking a backseat to what he wanted to do (or not do), nothing ever being "right" or good enough, and not knowing where I was going wrong or what I could do to make things better.
He's not diagnosed with anything, and most likely would resist the thought that there was anything "wrong" or different about him, but he has so many traits, plus there's a bit of ND amongst the DC (and I have a few ADHD traits as well).
I left him three years ago when I finally realised that it wasn't going to get any better, and that I deserved to be (a little bit) happier than I was. He took nearly a year to accept that I wasn't coming back, and still to this day doesn't understand exactly what it was I had a problem with. My final straw was speaking to him a couple of weeks after a joint counselling session where I had sobbed my heart out about feeling so lonely within the marriage, and he couldn't remember what it was I had cried about.
But, now I'm happier than I've ever been, living by myself with everything around me being things I've chosen for myself in colours and patterns I like, and not having to tiptoe around on eggshells in case a suggestion I make is taken as an attack. I've had a FWB relationship where I discovered that it wasn't me who was bad in bed (and that my orgasms were a joint responsibility, and not my fault when it didn't happen - apologies for bringing the tone down a bit!), and that I am desirable and attractive, both physically and emotionally, which I struggled to feel for most of my adult life with the ex.
The (now adult) DC report back that he's also (a bit) happier but seemingly struggling to work out why he's not finding someone to slot straight into the "wife box" someone mentioned upthread. But, I don't regret leaving, my happiness is my responsibility, and his happiness is his, I wasn't prepared to be a mum to his almost-toddlerlike thinking (you know, the "I want x so therefore Mummy wants me to have x, why is she being mean and horrible and not letting me have x" kind of negotiations you have to do with a three year old who's faced with a cutted up pear!). It took me over 20 years to get to that point though (we were together 30), but I'm so glad for my own mental health that I did. Within a week of leaving, my depression had lifted, my stress levels were way down, and my fibromyalgia wasn't causing me so much pain.
It's going to be very interesting to see how things are with the new bloke, he's so much more self aware of what he finds trickier and what he needs to do to deal with stuff, but most importantly for me, he actually listens to what I say, asks if it's not clear, and vitally (for me anyway) remembers what I've said previously. I'm going to hang around I think, as I'm sure there will be stuff I need to vent about if/as this relationship progresses, and that's always a lot easier with people who know where you're coming from. But also just to be the person saying "it's ok to put your own happiness lifejacket on first, a relationship can't just be all one person giving and the other taking, and yes, its horrible to think like that, but sometimes, when you've given all you can, making the break is the best thing to do"
apologies for the massive long post, there was just SO MUCH that resonated with me!
