Its called Gaslighting Uptoolate , and as you know its a form of emotional and phycological abuse . I presume he also uses other methods to emotionally abuse you by ignoring you , ignoring your feelings , shouting you down , twisting things , rewriting history ect. Sounds like he controls the finanaces too.
It is abuse , and its very serious , and worse , it usually just gets more and more severe , and as children grow and develop minds of their own they get targeted too. Im very glad to hear your thinking of leaving .
Most counselers will not counsel couples where this abuse is going on , but i strongly recomend getting some counseling for yourself. Have you heard of womens aid ? If not google them , they will be able to refer you to someone local where youll get some support , its free too.
Theres lots of websites , books ect that can help you , ive got loads of books that you are welcome to if youd like . Theres also lots and lots of links in my favourites, not sure if youve already seen them but yell if you want me to post them.
Ive been where you are , recognising it as abuse can be difficult , but thats exactly what it is . You really do deserve better than this.
