So sorry to hear your news and I feel your pain.
I recently found out my partner had been on a swinging site, not only having on Line sex, phone sex but also met up with people too. I don't know and will never know the full extent of his lies and deception.
Wish there was something I could say to make this easier for you. It's been 4 weeks since I found out & it still hurts like crazy.
We are still together, it's tough, a roller coaster ride.
You take care xxx
