To let her know

[ThePurplePeopleEater]

I have been sexting this guy on and off for quite some time however it transpires he has a girlfriend. I didn’t know until now and I have cut off contact. Should I tell her?

Yup. Send her a screenshots, start/end dates, apologise, explain you didn't know about her, and then disengage.

Yes, do the girl a favour, send proof if she asks.

Issue is there are nudes from him, which is illegal to share.

Smart woman, I would definitely not have thought of that.

Can you scribble out the nudes & just send the messages?

Surely there must be some conversations? Him asking for pics etc?

Oh plenty and asking to get his hands on me.

Christ no. Why do women get involved with this?!

Not your circus, not your monkeys.

Walk away. It's a girlfriend - not a wife!

Common decency maybe?

If your boyfriend had been sexting a woman pretending to be single, wouldn't you want to know?

I would explain the situation, send the screen shots of conversation and then block.

I totally agree with this ☝️. I would want to know so I dont waste any more of my time with the wrong guy.

What is the difference? Plenty of people don't get married these days. Girlfriends deserve as much respect as wives ffs.

wtf? So girlfriends don't matter?? they could still live together, have children etc for all you know.

Yes, tell her, apologise and say you didn't know.

Send evidence (cover the nudes) and then disengage.

It will save her wasting any more of her time on this piece of crap. Or at least she'll have the option of deciding what to do.

Telling the wronged partner is an act of revenge on him for involving you in this situation.
You have no idea what the potential outcome of telling her would be, there are some very bad possibilities for each of you.
Have nothing more to do with any of it.

Just block him and move on.

I would want to know.

Why hurt her? She hasn't done anything wrong.

Just disengage and move on. You have no idea of the circumstances of their relationship and I don't know why you would invite that into your life. Plus it prolongs your involvement in his life.

If I was the girlfriend I'd want to know and I'd appreciate being told.

Also understand people suggesting you shouldn't get involved further if this could make things difficult for you in any way, though!

One very good reason is that she probably needs an STI test asap.

What’s the relevance of her being a girlfriend not a wife? Judgy much?

I don't think you can catch an STI through a phone.

Op isn't the one hurting her. Seriously!
All OP would be doing is the decent thing in letting this woman know something which may potentially save her from wasting years of her life.

Don't be naïve, if he's sexting one woman chances are very, very high he's fucking others.

I highly doubt I’m the only one sexting either.
