I really don't know where else or who else to ask.
DH and I have been together for nearly 16 years. We got married and had children pretty quick. Shortly after DS was born DH went to the doctors concerned about memory problems, he was diagnosed with depression, he did CBT and sat with the diagnosis for a while and didn't feel it was right. After DD was born he went back to the doctors again and was diagnosed with Bipolar Disorder, he went through a whole host of different medications, including lithium but ultimately felt that this still wasn't right. After a number of years he went and saw another doctor and was diagnosed with ADHD, again did medication and ultimately stopped as he felt they weren't making anything better. He now believes he has autism, but has done nothing about it, although as an adult I'm not sure much can be 'done'.
For the last 5 years we have been having a very difficult time with our DD, who earlier this year was diagnosed with Autism with a PDA profile. DH suspects he has Autism due to their similarities, but still hasn't done anything about it.
DH does work a full time job, but I have to admit I have to support him an awful lot to do so, we have actually always worked together (although in recent years I had to give up work, and he works from home), so being together all the time is normal for us. Having said that, I feel like it is all catching up with me. DS is in therapy, he has anger issues and depression, DD is a full time job, she needs an enormous amount of support and it is incredibly draining.
DH feels more like one of the kids than a partner, where I have to do everything for him, write him lists, constantly remind him of things, pick up the slack when he just doesn't do things, which is a lot. He has no sense of personal pride, if I don't tell him to shower he can go weeks without one, I have to tell him to get a hair cut or that his clothes are falling apart. I do love him, but having to look after him like this is not attractive. I don't mean physically, he is a good looking guy, just everything I have to do in order for him to function. Whenever I've tried to talk to him in the past, he gets super defensive and 'admits' how useless he is, how he knows all of this, and always ends up saying I will go back to the doctor but that just doesn't happen. How on earth do I try and fix this?
I could write a huge amount more but I would be here all day.
