To tell his partner we slept together?

[kuzmichtm]

Please be kind, I know I've made a mistake.

I have a 15 year old DS with my ex H, we split nearly 6 years ago and I got into another relationship, I have a 18 month old with him but we split when he was a couple months old as he was very abusive towards me. He doesn't have any involvement. My ex H has been helpful, he had DS1 living with him as there wasn't any space at my mums, he looked after DS2 on occasions.

He came over last night to bring DS1’s school bag, DS1 was out and my mum had my youngest. I invited him to have some drinks and he agreed and we ended up sleeping together.

He's been in a relationship for 3 years but I'm not sure where I should tell her or not.

WIBU?

I wouldn't tell her, unless you and husband think you are going to suddenly make a go of things again.

It will cause unnecessary drama for your DS15 aswell, and potentially throw him off track.

Just see it as a moment of madness, and try to free up some more time for yourself and your friends.
