I don't know OP situation so I'll reserve some judgment. However, I'm really tired of rhetoric about how alimony is always some evil scheme made to specifically destroy men in divorces.
When people get married, often times one of them gives up their job and start performing unpaid labor. Sometimes neither of them give up their jobs, and one of them still has the majority of household burdens forced onto them, affecting their career and performance.
Alimony is a form of compensation for the unpaid labor and it's impact on that person's career. More often than not, when people say 'my ex wife is taking all my money', what they are really saying is 'I deserved free labor at the expense of my ex wife'.
Granted, it's possible that OP could be a domestic abuse victim in which case alimony is a whole other form of fucked up. But if that's not the case, then please stop.
Good is not the enemy of perfect.
