AIO about my husbands flirty texts with his massage therapist?

My husband started seeing a massage therapist in around October last year. The first time he saw her he said she was the best one he’s ever been to and then went like 3 times in one week. Then it was only a couple times between then and January of this year. He hurt his back so went to see her again a couple weeks ago and was there for 3 hours which I thought was weird… I didn’t think registered massage therapists did massages that long. He then went again last week for another hour.

When he came home from the last one he was telling me how disgusted he was because she was explaining to him how she was sort of an escort and guys would pay her lots of money to do weird things like pee on them.. which is beyond disgusting. It seemed like she was trying to feel out of that’s something he’d be into by telling him all that.

He said he was so repulsed by her and wasn’t going to go to her anymore but then I found on his phone he was texting with her after this last massage and they were going to possibly meet up when snowboarding when I wasn’t there.

I noticed he had deleted all of their messages so too I went to the recently deleted and recovered them all and his messages were very flirty. He even offered to pick her up coffees or smoothies before some of his previous massages. He says it’s nothing but I dont believe him snd have lost all trust 😔
