By the same token though, such things happen in bio-families too. My husband's father is dying of cancer, like he won't make the year, yet my husband won't speak to him, nor his father to him. His folks were planning to divorce but his mom became pregnant with him, his Dad blames him for "ruining his life" (and I've actually heard the man say this, at our wedding no less.) His mother is a "traditional" woman who basically just ignores it all happened out of idk loyalty to her husband or something - I don't get it honestly. His Dad's a drunk, abusive, rude, unemotional... I tell my husband he hasn't "belonged" to his father since he was 16 and moved out to join the army. Its fucked up that this /still/ effects my husband, he's 45... Parental abuse doesn't ever go away, it permanently scars kids emotionally. Tragic I suppose, but on the other hand, it also makes these same kids stronger, I think in most cases, so is it "the worst thing in the world"? I'm not so sure, my husband would not be who he is today without it and he's a good man, an asshole at times for sure, but its a "good intentioned" asshole-ness that I can understand, and even grudgingly respect.
It actually makes me laugh at times, he's very much like my father (actually my step-father, but he raised me so I call him father) when I was growing up I couldn't wait to get away from my father, couldn't wait to "escape" the "militaristic" environment (father's a general.) I married my HS sweetheart, he was a sheep, good man, great father (we had two kids then got fixed and I'll never regret that choice.) Yet I find myself more... content, more in love, with my husband even with all his stupid "military" shit. I grew up basically, realized that my father was teaching me things that school doesn't, things that don't seem to matter but they create a pattern of thinking. I thought my father was abusive, but in reality he was doing what was best for me. The problem with today's society is that these kids never grow up and reflect on the lessons well meaning folks tried to teach them, they only "rebel" they only "fight the man" and that kind of "thinking" is not conductive to having a "successful" life - however one wishes to define success.
