Hi Mary73 - first things first

It sounds like you're mentally and physically exhausted. Are you able to actually get away from your husband at the moment? Are their friends or even family you could stay with? I worry that if you stay in an environment with someone who is so unsupportive and immature you could end up retaliating in a more extreme way. Who is supporting you at this time? Do you have a therapist? If you are on meds do you feel the amount might need adjusting?

As for dealing with your husband, i would state outright in as calm and concise a manner that him being near you at the moment is proving damaging for the pair of you and that if he won't leave you're prepared to take action instead (whether this be staying elsewhere for a bit or looking at a more long term solution). What if anything is your husband doing to support you? I understand that living with someone whose experiencing mental illness can be tough but this man is your husband, its not as if he's said to you he needs to take a break because he too is finding it exhausting - instead he's acting like a child who shows little concern for either you or your feelings.

I think removing yourself from the situation for a bit is the best thing to do - when you're away your husband might come to his senses but even if this doesn't happen it will give you a chance to really think about your relationship and how you want to progress from there whether it be moving out permanently or, if your husband agrees, seeking some form of marriage counselling for you both. I can only wish you the best - please remember to take care of you during this time, we are all here to lend an ear and even if you just want to vent be assured that this is a safe place to do so.
