Untraditional families can be even closer than traditional ones, but that doesn’t mean they are straightforward relationships.

See why this family is going through even more emotional chaos.

AITA for only taking care of my (full) little sister?

I have a younger sister, Lara.

I’ve basically raised this girl like my daughter.

I love her like she’s my own child.

Our mom died when Lara was a year old and I was 15.

Our father was a wealthy man with a revolving door of younger women, who my sister grew up resenting.

It’s about to get super complicated.

Whatever our father was, he loved us both very much.

He was a workaholic, which left me caring for my sister most of the time.

Even though she had a nanny, she had extreme separation anxiety.

When I started college, our father bought me an apartment so I didn’t have to stay in a dorm.

It turned into me raising my sister throughout college and business school.

She stayed at my apartment with her nanny during school hours, and I took care of her when I came home.

I never missed a single competition or spelling bee, even through school, which I don’t regret.

That’s what I mean when I say I raised her.

About three years ago, our father started dating a much younger woman (25F).

She got pregnant and gave birth to a daughter.

I was never involved with the kid.

One time, I took my sister to visit because our father requested it.

It ended with her being an emotionally distraught mess for a week.

She felt like she was being “replaced.”

Any time I brought up the kid, she would cry.

So I refused to see the kid again.

Our father died unexpectedly six months ago.

He never married the woman, and she didn’t get a penny in the will.

The kid got a small lump sum, but nothing like the trusts my sister and I received.

I don’t think he cared for the kid very much, but the woman wanted it.

I used to joke to my sister that the girl was just a “compromise kid.”

Then things got even more emotional.

Lately, the woman has started badgering me.

She says she can’t raise a child on her own and it’s unfair that I’m protective of my sister but won’t do the same for my “other sibling.”

I corrected her and said I had no relation or obligation to her child.

Her child being around hurts my sister, and she is my priority.

She got angry and said I can’t spoil one sister and neglect another.

She said her child doesn’t have a father now and needs a male presence.

I told her to contact my lawyer.

Then she somehow got my sister’s number and sent her texts calling her cruel for “keeping” me away.

I had to be up all night consoling my sister, telling her I wouldn’t see this girl and she had nothing to worry about.

I called the woman again and threatened legal action if she kept harassing my sister.

Now she’s calling my aunts and uncles, saying I’m vindictive and cruel.

Here is what folks are saying.

I think they all need therapy.

I’m not sure I’d put it like that…

Can’t allow a minor to be harassed.

Yes. Nothing changes that.

That would explain things.

I hope they all get the help they need.

Because no one sounds exactly healthy here.
