She can tell you whatever she likes but why do you take any notice ?
people always take notice of those whom opinion they value. this is someone who has shared a life with, loves, trusted, has started a family with , it hurts when people this close to you can make you feel so useless , undermined and worthless.
its easy i guess for others to say walk away, leave, and yes it can be damaging to self esteem , my own advice would be to leave, find someone who values you etc, but you do have a family and i assume (?) the relationship wasn't always this way? something changed, confront her, your feelings , say how it makes you feel, say you will not accept living this way anymore (or you will be miserable and for what?) don't ignore it, offer to resolve things, work out at strategy together
if it fails then you know ou have tried for yourself and your family and then move on
are you sure its not her own insecurties casuing problems, people tend to get needy and demanding when they feel like they are failing and letting others down, they need to control others to feel they are accomplishing something and in charge
gosh it sounds easy when you type it hey? hope you have some support from friends or family
