I don't think it's weird at all. I'm in the same boat, except I was the oldest and the one who took the brunt of all the physical and mental abuse. The younger kids know it BUT they just don't talk about it. I am the oldest of 5. Anyway, I think it's understandable that you don't want them to know anything more than what they know. I am the same. I told my sister that once I was suicidal and she looked at me in total disbelief....so I've not really talked about it since. It's like they know something is wrong with me but they never bring it up. My husband is sorta the same too. He is the youngest of many children and his oldest sibling was 21 when he was born, so half the kids were grown before his dad started drinking heavily and abusing them. The older kids want to believe they "had it so much worse" than the youngers. But they are wrong.
It's the others that are weird, not us. Besides, if it's any consolation, you have us

and I promise you PROMISE PROMISE PROMISE I'll be here for you no matter what you do or say! I'm just that way
Take Care of yourself hun,
Many blessings sent your way,
Kimberly.
