Every minute together is SO complicated, doesn't feel like a life

I am so overwhelmed with how complicated this is - to try and change every minute, every interaction, every hour of every day of every month of every year - and at the same time ignoring the chores left undone, feeling ignored, feeling hopeless, keeping my lips sealed shut when he fails YET AGAIN at something he promised to do. I have to think about every word that comes out of my mouth, because he may be "offended" or become defensive because of his own baggage. I am TIRED of feeling like his enemy.

I did not sign up for this kind of relationship. I'm not sure I can continue this extremely complicated, exhausting way of life.
