Ok so a few years ago my dad and mom split up. They’re still legally married but don’t live together anymore and my mom has a boyfriend, who my dad knows about and is comfortable with. My brother loves my mom’s bf and his son, I don’t mind them either. It’s all good. My dad and my mom also get on and are friendly with each other, and negotiate custody well, it’s 50/50. He sees us half the week, my mom the other half. There’s no child maintenance or anything.

Today, whilst he was in the shower, I saw a notification on my dad’s phone.

A message on Facebook.

I swipe on it.

And I’m shocked at what I find.

Messages for months on end two kisses ‘xx’ after every message and much more.

You can tel that they’d met up almost every night and gone places together. He even mentions me and brother, which I’m not too happy about; you’ll see why.

I keep reading, there’s some real explicit stuff, messages like ‘I’ll lick you like a lollipop and caress your balls.’ And much worse.

See I wouldn’t care if this was from a woman that I’d never met, seen or heard about before, in fact I’d be happy that he’d met someone because he’s a nice guy.

But it’s my mom’s ex-best friend.

A woman who literally helped her through her divorce and break ups. We’d even been on holiday to Greece with her for a whole week with her daughter.

Her daughter who’s in my class, we used to go round to each others house all the time, we’d look after her and they’d look after me because they’re both busy working women.

There wasn’t really a dramatic event that split them up, they kind of just got put off each other and my mom realised she was a sneaky women who used men just for attention and sex.

This is clearly what she’s doing to my dad, not to be rude but he’s really overweight and smelly. Maybe she’s doing it as revenge to my mom for not sticking with her when she had no friends due to her sly actions.

Not to mention her daughter, who as I said is in my year at school. She bullied my best friend and spread rumours about her and now literally everyone hates her. She’s even blocked me on Instagram when I had nothing to do with it.

Plus she’s one of those basic popular bitches who posts snaps of her self everyday and explicit mirror selfies and flirts with all the boys. I don’t hate many people but I sure hate her.

And she gets it from her mom, which is why my mom doesn’t like her mom - they’re very similar.

This woman is such a sly bitch and she’s so needy after her husband left her even though he pays her tons and tons of child maintenance.

Basically what I want to know is should I tell my mom about it, and if I do, should I show her the explicit messages?

The thing is I don’t want my dad to never trust me again for reading his messages because she will definitely confront him about it.

BUT I think it’s completely inappropriate for him to be fucking his ex-wife’s best friend, and secretly, when my mom tries her absolute best to be respectful with her new bf and honest about him.
