Yikes, it totally sounds like Battered Persons Syndrome. Well that kinda freaks me out, but I'm not battered. Emotionally and verbally abused, yes, but not battered. :/ And there is no tension aside from the alcohol.
The syndrome develops in response to a three-stage cycle found in domestic violence situations. First, tension builds in the relationship. Second, the abusive partner releases tension via violence while blaming the victim for having caused the violence. Third, the violent partner makes gestures of contrition. However, the partner does not find solutions to avoid another phase of tension building and release so the cycle repeats. The repetition of the violence despite the abuser's attempts to "make nice" results in the abused partner feeling at fault for not preventing a repeat cycle of violence. However, since the victim is not at fault and the violence is internally driven by the abuser's need to control, this self-blame results in feelings of helplessness rather than empowerment. The feeling of being both responsible for and helpless to stop the violence leads in turn to depression and passivity. This learned depression and passivity makes it difficult for the abused partner to marshal the resources and support system needed to leave.[8]
Feelings of depression and passivity may also be created by lack of social support outside of the abusive situation. Research in the 1980s by Gondolf and Fisher found that women in abusive situations increase help-seeking behavior as violence intensifies. However, their attempts at seeking help are often frustrated by unresponsive extended family and social services.[9] In a 2002 study, Gondolf found that more than half of women had negative views of shelters and programs for battered women because of negative experiences with those programs.[10]
