When it comes to family, it can be hard to speak up when you know the truth will hurt those close to you.

When her sister’s boyfriend flirted with her, she thought being honest would protect her sibling, but she was made out to be the enemy while her creepy boyfriend got off scot-free.

You’ll want to read on for this one.

AITA for telling my sister her boyfriend hit on me and “ruining” their relationship?

I’m 20 and my sister’s 27.

She’s been seeing this guy who’s 47, which is already weird, but whatever.

I’ve never liked him.

He gives me the creeps, but I’ve just kept quiet to keep the peace.

But one day, his creepy behavior was on full display.

A few weeks ago, we were at my mum’s and I was in the kitchen on my own.

He comes in and starts saying stuff like, “If I were younger,” and “Don’t tell your sister but I’ve always thought you were stunning.”

I literally just told him to stop and walked out.

This was eating at her, so she decided to come clean about what happened.

I didn’t say anything at first, but it kept bugging me, so I told my sister.

I was calm—just said she deserved to know.

But her sister didn’t want to hear it.

She completely flipped.

Said I must’ve taken it the wrong way, then turned it around and said I was flirting with him.

Apparently I’m jealous and just want attention now.

Now there’s a ton of tension in the family.

She’s not spoken to me since.

My mum believes me and is completely on my side, but my sister’s telling everyone I tried to come on to her boyfriend and ruin her relationship.

But she resents being painted in such an awful light.

I want nothing to do with him.

He’s nearly older than our dad and makes my skin crawl.

I wasn’t trying to start drama. I just didn’t feel right keeping it to myself.

AITA?

Did she do the right thing by being truthful with her sister, or should she have kept this to herself?

Let’s let Reddit be the judge.

Her sister’s anger was definitely misplaced here.

This user feels sorry for her sister.

Her sister’s boyfriend’s behavior is even more toxic than it appears.

This guy is just plain bad news.

Her words may have caused a rift, but at least her conscience is clear.

Someone’s ruining the relationship alright, but it’s not her.
