To say something to him?

[Flowercurtains]

I've been with my partner a few months. We've moved quickly and I've met his son a couple of times. Who is 9. Which has gone well. So right at the start, his uncle died. He was like his father so he took it quite badly. Around this time I met majority of his family as everyone would be around to send their condolences.

Around this time I met the mother of his child. Who is married by the way with two other children. I did notice that my partner and her shared a very close relationship and she would be quite affectionate with him. What I mean by that is hugging him constantly and rubbing his back. I didn't mention anything at the time because he was grieving. But afterwards I did asked him if anything had gone on between them in the past few years. Out of curiosity. He sweared no.

OK so this is where I've fucked up. He fell asleep. His phone buzzed. I picked it up and went through it. I didn't see anything during the time we've been together but I've seen texts messages back and forth between the mother of his child. These are very sexual in nature. These texts messages are from a month before we met.

I feel betrayed as he swore to me that nothing has happened in years and I had nothing to worry about. But it seems like they have been intimate in the last six months. But on the other hand I know I was wrong to go through his phone.
Should I say anything to him?!

God no but id be saying goodbye!
The trust will definitely be gone now

Cut your losses. He’s lying to your face. She is cheating on her husband with him by the sounds of it, neither of them have any loyalty or morals.

confront him with proof if it’ll help you for closure but honestly you’ve been with him for months, don’t waste any more time.

Tell her husband and block him.

To be honest, I don't even want to get involved and tell her husband. I didn't know if I was wrong for feeling betrayed, as I wasn't with him then but at the same time I've asked him more then once. And he's sweared blindly nothing has happened In years. But I had an inkling. I knew.

I wouldn’t bother. It’s been such a short relationship that seems to have moved incredibly quickly (she’s already met his son 😵‍💫) - I’d just leave. He’s not been honest when asked a simple question, he wasn’t with you at the time of these messages being sent so why the need to lie?
He’s not a keeper.

Exactly. He wasn't with me so why lie? Although he's probably lied because he knew i would be out. I do feel very very guilty for invading his privacy and looking through his phone though.

You went with your gut instinct and weren't wrong.
I once did the same and saw current msgs with an ex and it was a straight goodbye!.
When you know, you just know and if he's lying now he will keep on lying

Yeah it's not ideal but you wouldn't have found out otherwise. And it was important to know that he's been lying about the degree of intimacy between him and his ex. You've only been with him a few months, very little investment, just get rid - you can do better that a man who lies to you.

P.S. do not say anything to her husband.

I wouldn't specifically say anything when I broke up with him. Just a vague, "The relationship you have with your ex has made me realize we are not going to work out together. Bye" would suffice.
