When I try to think about it, I really have no clue what my wife enjoys doing... I can't think of any interests/hobbies/etc. that seem to bring her any sort of satisfaction... I feel like she really has no identity of her own.
Hard to put into words what I see sometimes, but my ubpd traits SIL appears restrained, has flatness of character, reduced curiosity/enquiring mind about life, mental rigidity/lack of conversation depth, disinterested in controversial topics which would normally stimulate conversation, lacking in some kind of exuberance and 'colour'. She is however an intelligent woman, successful in her career...works with directors and shows flair when she does engage in something that is pushed in her direction, that she maybe wouldn't seek out herself. Maybe she only shows this character rigidity/flatness with me and my brother experiences something different...I don't know. There's probably something more interesting buried underneath somewhere but she can't reach it. My brother being enmeshed with her and under her influence shows signs of identity loss and disappearing authenticity.
I slowly started giving up a lot of things that made me happy, because i'd get guilt tripped by her to not do them...I've slowly started regaining control over my life...
Poor is the man whose pleasure depends on the permission of another
