Besides cheating, what reason would make you want to break up/divorce your partner?

We all know the big reason is cheating, but are there any other reasons that might do it for you to want to end things? For me, it would be an egregious lie that affected my life, like about the finances (for example, ruining my credit by putting us in debt with spending without telling me or having a secret bank account for themselves that has been taking funds from our joint accounts). I think another reason might be if they admitted just not loving me anymore or becoming abusive.

So how about you? What reason, besides cheating, would do it for you?
