Wife is ready to return

I shared my wife for a few years and we recently took a break. She is very into connection and got attached to most of her bulls which was an issue for me. We had trouble setting hard boundaries and she fell for a guy.

Didn’t plan to return but she is telling me how much she missed it. Our sex life has been good but even guys smaller than me and ones that don’t fuck her as good she gets wetter for. She just loves fucking outside the marriage. She tells me that monogamy is boring. I feel the need to let her play. Maybe in a new format that’s safer for us
fine for her to let as many men as she wants fuck her but on your terms and with your knowledge. Ideally with you watching
 
Maybe I am wrong but I don't get "cuckolds" who say and think they have the right to set boundries on what the wife does. In my world as a cuck my wife does what she wants. I have no say. Isn't that what the cuckold lifestyle is all about?
Having a wife fuck lots of other men is not necessarily a cuck lifestyle. Many of us set the rules and let the wife open her legs as often as she wants under our control; even if she might be doing the fucking without us present
 
It all seems fine until "feelings" enter the situation. Surprisingly, this is far from limited to the hot wife/gf. That's just the one that gets lots of coverage. No one talks much about the "feelings" a husband/bf gets when his wife/gf admits to having an emotional connection to their bull/bf/fwb.

It doesn't seem to matter if your wife has the freedom to do as she pleases without care or concern, or if you have mutually established rules/boundaries. Once "feelings" enter in, there is a new layer of uncertainty that a husband/bf gets. He now has HIS own "feelings" and they are usually not comforting. He now has whole new ground to consider and ruminate on. Will she leave me? Does she love him more than me? Are they doing more than sex, like going to movies together or going to parties together or hitting the bars together? Will I have to accept that she would rather do those things with him instead of me? Will she be staying with him for longer periods of time? How much time will I have to be alone? All those thoughts and more will invade the thoughts of a husband/bf in this situation. "Feelings" will arise from the tempest of thoughts.

Some husbands/bfs get off on and thrive on the angst and mental torment. Other husbands/bfs are crushed and can't take it.

I'll fall back to my steady notion that it takes a really smart and sensitive wife/gf to be aware of the affect she has on her husband. She should know the things that turn her husband/bf on AND the things that ruin his desire. What good is being a hot wife if you're no longer married? What good is having a hot wife if you're always expecting less and less attention from your wife sexually and socially?

In the OP's case, he's been there and done that. ANY TIME you do ANYTHING sexual or not, if you like it but had mixed results you want to analyze the situation and figure out what would have made it a better experience. This concept has universal application. It works on bowling or sex, you name it. Since the OP's wife is initiating the return it would be good to discuss what would be different this time to avoid the previous results.
