To play devil's advocate for just a moment... Let's say you were married to a woman and for whatever reason you no longer wanted to be with her. She was a house wife and relied on you for all the income. She is now on her own... She shouldn't have some kind of financial support until she gets her life in order?
It depends on the circumstances. In the seemingly innocent scenario you present, then yes it's understandable to help her get on her feet. However, if I marry someone who refuses to work one month into our marriage, and after years of her being a slob and me trying to help her get a life going for herself by spending money on education programs she doesn't complete, let's say she convinces me to have a child, and then before or soon after birth, she takes the child and branch swings to another man hundreds of miles away who is sliding her money. Does it seem fair that I have to pay alimony to this worthless human being?
A bad case scenario, but it happens. My own sister has repeatedly screwed men over with this tactic. She has 7 kids from 5 different men. She has not worked for probably 13 years and has been married 4 times. When the husband can no longer provide enough for her, she starts saying what a jerk he suddenly is and then trades up to the next tool by getting pregnant and trapping him. Her latest ex husband even adopted another man's son. She left him because they were tight on money and he insisted she started working. She wanted to have another kid. He got a vasectomy. So what did she do? She cheated on him and got knocked up by her current husband who makes the same amount of money as her ex husband. But now she gets child support from multiple men and tells everybody on Facebook what a wonderful provider her new husband is. And she does whatever she can to spoil her exes' relationship with their kids.
Because of biology, women are in a good position to pull stunts like this. And some take advantage of it.
