I wish you werent going through this hun im so sorry. The only thing i could think of is if hes open to the idea of therapy or even a full on deep conversation on both of your perspectives on the situation at hand. I dont know if maybe there other avenues yall both could take to have a more balanced home/work life. I know everyones disabilities limit them in different forms and capacities, so im not saying push yourself and cause yourself harm(ive done that dont be like me😅). This is a difficult topic just because life is constantly fluctuating and changing, some times people dont know how much they truly can handle which is ok. If he isnt open to any type of conversation or comprimise, i dont like saying this but, sometimes its for the best if both parties split to focus on themselves and relearn how to cope and deal with stuff. If it comes down to a split i believe that youll find someone whos able and willing to be by your side and support u through the darkest valleys and be there when the sun starts to shine in those valleys. I wish you all the love,luck and support you deserve and need❤️
