New Member - Journey So Far and big Step back

Me (m33) wife (f32)

married 10 years next May - together since high school (16years total)

She has only been with me

First step - admitted about the fantasy by telling her about a mfm dream with my best friend

this eventually led to a night that she admitted she thought I was going to start something, but I chickened out

2nd Step - adding dildos (1 smaller, 1 bigger, and an extension) to the mix - writing erotic stories for her that revolve around the kink

3rd Step - send her porn to masturbate to and have watched her then joined

4th Step - bought her hot wife panties (she surprised me this weekend with them for a date night)

5th Step - Woke me up one night after a date night and told me to get the chair and she performed for me with both dildos as I watched then she made me finish her off

6th - grabbed the bigger dildo this weekend for sucking (3rd time in the past month this has happened) but eventually got her to riding it

Felt stuck in this moment....but then made a big mistake

Previouisly I had a friend that we shared photos back in forth of his sexcipades and me of my wife (this was after a rather rough patch in our marraige and apparently she only did it to appease me)

well i sent him a photo of her after she was in the shower (mostly covered with an emoji, but could see her ass for the most part

i did not tell her until that night as I was going down on her and then brought it up...my night did not go well after that and then she bashed on the uses of the toys etc. and asked if I respect her and our marriage.....

So now I am in the recovery phase

how do you guys work through missteps and build back up?
