The answer is usually money?
Obviously some women will be staying for a lavish lifestyle provided by a high earning husband but I believe that the majority will stay just so they don't have to bring their children up in poverty.
If a husband is lazy/thoughtless/untidy etc is that enough for the majority of women to give up a second full time wage in an unsteady economic climate? It wouldn't be enough for me to leave but the cries of LTB on here are always abundant.
I've seen it a lot on the mother's day threads...partners/husnds not doing much for the mother of their children and the obligatory LTB posts that follow....I just don't see anyone leaving over one day when it would make the other 364 days of the year such a struggle.
Obviously this does not relate to abusive relationships but aibu to think most of us will deal with 'good enough' but not spectacular partners to keep us in a certain lifestyle (ie not poverty rather than shopping at Tiffany's every weekend!)
