Neither of them work so BOTH OF THEM should have made sure that contraception was in place. Unless she lied about being on the pill then he is equally responsible. He should have worn a condom - it takes TWO to have that discussion,"are you on the pill dear?" "no, ok, i'll use a condom" or is the man just to assume the woman has it taken care of.
From what the OP says, this woman doesn't sound capable of caring for her child - that is very very sad. If her mental health issues are as severe as is made out, i am sure social services are already involved.
I'm very skeptical about this thread to be honest. If the OP hadn't been so vitriolic about this woman i would have probably agreed with you Snorbs, as you are right, it is not just women who are the victims of domestic abuse.
Either way - this woman needs help, but i think she will wait a long time before she gets it from her ILs.
LittleMrsHappy - have you ever suffered from depression? Have you any idea how ridiculous your comment that she should "help herself and not be reliant on others" is? Yes, ultimately people with depression don't tend to get better until they get to the stage when they can help themselves, but sometimes people are so low that they simply can't.
I would hve been equally suspicious of the OPs motivation if she had been talking about a man as she would a woman. She just wants to use mental illness as a stick to beat her with - i am not the only one to see that straight away.
The most important thing is the child - so, social services need to be informed - if she indeed isn't coping and the OP can offer a stable home for the child while this woman gets help or whatever happens then that sounds like the best solution allround.
