Most OPs that post about unhappy marriages want to know one thing: "what is normal in relationships, what can one expect from a good decent viable relationship?" And a chorus of Mumsnetters come back to reply:
you can expect partners who treat each other as equals and respect each other equally
you can expect an absence of physical violence
you can expect an absence of fear of the other partner
you can expect never to be humiliated or denigrated in public by your partner
you can expect not to have to listen to violent or abusive language
you can expect your partner not to put you down in front of your children
you can expect never to need to fear for the safety of your children from your partner
you can expect that your partner will pull his/her weight and want to do his/her best for the family
you can expect to feel cherished and supported when you are low or unwell
you can expect to feel safe from betrayal or unfaithfulness
you can expect an equal say in questions that affect the family finances/lifestyle/parenting etc
you can expect an equal amount of leisure time and equal freedom to choose your friends and hobbies
you can expect equal access to money/everyday comforts etc
This is what millions of women have and there is absolutely no reason you should put up with less.
