She hates him a lot. He and I are... ok. Should I reach out and message her or leave things be? I found her facebook and I have a niece who is a couple years old and maybe a nephew? IDK.

I think you should! You never know how far a simple "Hey, I'm here for you" can go.

I feel like it's a bit awks too though. Like, we have spent 2 weeks together EVER. and the whole time I was babysitting her and she would walk up to strangers at the Y and be all "That's my sister but we have

different moms. That's why she is white and I am black" and I was like... um yeah hi stranger

that was 16 years ago.

Doesn't hurt to reach out, and if she doesn't want to connect at least you tried!

I sent her a message with a happy birthday since today is her bday!
