I’ve fallen out of love

I’ve fallen out of love with my boyfriend of three years and father to our two sons. He’s cheated on me and been violent in the past and I feel like it’s all accumulated to me not having that passion anymore. I have no desire to do all the necessary work it take to keep our relationship going (because he definitely doesn’t do it)... I feel guilty for somehow being able to love him through infidelity and his anger issues and his alcoholism but now that it seems we’re on a calm place, I have absolutely no romantic feeling for him. He feels like roommate. I can’t continue like this...
