I think it is a little more subtle than that.
I believe that some women are brought up with little or no self-esteem. They see their fathers treat their mothers badly, and this becomes their relationship model. When the meet a similar man who treats them badly, then all is well because in their experience, this is how the world turns, so all is nromal.
For women like this, abuse and conflict are a way of life, and in a bizarre way, it become reassuring, and they are able to tell themselves that they love the man, and he loves them, even though all the objective evidencec points to the opposite opinion.
My advice would be to find yourself another girl - life is too short to take on baggae from another relationship - and this set-up has 'grief 'written all over it.
Walk away. Now.
