Following this thread with interest. AIBU5, I'm in a very very similar situation. It's incredibly hard. It must be, because I'm researching it on Mumsnet, which generally is a platform which I despise, lol.
Living with an undiagnosed and in denial autistic bloke brings up unique challenges for a NT woman. I don't think this area is discussed much because we are as a society, only just switching on to the problems faced by autistic people and are, quite rightly starting to focus on those, as autism has not been properly understood from an equalities perspective. Autistic people face discrimination, no doubt about that.
This means it can feel like jumping the gun to consider how painful and challenging it can be as a NT trying to raise a child and live with an ASD. I have read some posts from autistic people that show how complicated it must be as an autistic person, to try and accept that it is possible for someone to be both autistic and to suffer discrimination, at the same time as being difficult, upsetting, negligent, emotionally abusive and generally out of order themselves. And before you say 'non autistic people can be all of these things' yes of course they can. But we're talking autism here and the unique challenges of this.
Why is this so difficult for autistic people to get? I think it is because it is not a binary situation by any means.
Just because it is a challenge to be autistic in the modern world, does not mean it should be easy as a NT to live with an autistic person. You can't say "I have a hard time, therefore you're not allowed to have a hard time'. That doesn't work.
Here's the truth. Autistic people have the right to feel sorry for themselves for being misunderstood, but also need to be aware that when they have decided they are victims, they may be wrongly blaming others inappropriately, to suit black and white 'I'm right, you're wrong' thinking. Autistic people are prone to binary thinking which is often inappropriate. Autistic people often cannot consider the feelings of others when they need to, or express compassion and understanding when they need to. Or take responsibility for mistakes when they need to. This can be almost impossible to deal with in an intimate relationship and can even seem abusive to a NT.
A common feeling amongst NTs who live with an ASD therefore is loneliness and feeling unseen and unsupported. Autistic people can struggle with communicating. All these things are crucial for relationships.
Then there may be a host of other problems too. You can slam me for generalising of course, but if you have an autism diagnosis then many generalisations have already been made about you by medics or psychologists or teachers, and you have probably accepted at least some of them at some point. So try to step back.
AIBU5, all I can say is, I feel your pain! I'm hanging in there ATM for our child because to leave right now would tip the cart over and we would all be devastated. The day to day running of the house would collapse. But give me five years, and I'm afraid to say, I'm out of here. Sending you solidarity and fortitude.
