My dad is dating my sister's close friend.

I'm a 19 year old male and I have a twin sister who's 19 years old as well.

Our dad is 38 years old.

I found out early in the month that my dad, who's been separated from my mom since the end of summer,

has been dating my sister's friend, Bre, who's 20 years old.

It was weird to find out that they were dating, but I told them they had to tell my sister or I would.

And I was really hoping they'd hold up their side of the deal because I have no idea how to tell my sister about this,

but they didn't. Every time they said they were going to, they didn't, for whatever reason.

So now I have to tell my sister. I can't keep a secret from her longer than this,

but now I have reasons to believe they're expecting, but I'm not 100% sure.

Should I mention this to my sister as well or keep it out?

It's something that obviously time will reveal anyway, so I don't know if it's worth it to upset her more

with something I don't know is true. So should I tell my sister, our dad is dating her friend.

Fast forwarding into the future, there's actually an update which says, I just did it.

I told my sister, she was upset. She started crying.

I think at first she was most upset because her friend lied to her a lot to keep this relationship

a secret, daily lying. So she was really upset about that.

Then the weirdness of it all set in and she got really, really upset.

She asked me if we should tell our mom and I really don't know.

I don't know what the right move is here, but I guess I'm glad my sister knows now,

so we can figure it out together. My sister hasn't spoken to either one of them.

My dad or her friend, she just blocked both their numbers and I did the same.
