<human>: Give me the gist of the text in a nutshell

I (23M) screwed up big time with my wife (21F) of 2 years. What happened is I have this very old friend (21f) whom I have known for years, we have always made sexual type jokes with each other  and it has never been a problem. I then got married and my friend and I kept going on the same way, I didn't try and hide it from my wife or anything but I didn't exactly share the jokes with her. 

Well a few months ago my wife found out the things that my friend and I were saying to each other and understandably she got upset, well I told her I would lay off and not talk to her as much and for awhile I was doing pretty good. Until recently

I started talking to the friend again and nothing changed we acted like nothing had changed ever. Today my wife found our most recent conversation and well I feel awful and I've lost all trust with her. I don't want to lose my wife and I do want to fix this. 

I have not had an affair or anything that can be called physically cheating. What my wife feels like I have done is breaking a promise and talked about sleeping around with other women. 

What I have done so far is I have actually deleted my Facebook which was the one means I could talk to the friend of mine as she doesn't currently have a working phone. I also did block her old number just incase she gets it turned back on. She is a good friend but we have grown apart and to me that doesn't seem like a big deal to save my marriage. Is there anything else that reddit thinks I could do to help get the trust back. I know it will take time but I want my wife seeing that I really am trying to get better.
<bot>: I broke a promise I made to my wife about another woman and lost her trust, anything I can do to help get it back?
