I thought about some of the dynamics you have shared on this forum and from your past, and it has made me think of a few things you may want to talk to her about. Given her latest desires in enjoying controlling your orgasms, maybe something you need to look into is a female led relationship. It would allow you to exhibit both the alpha and beta desires you have, and yet keep the spark alive with or without Paul around. You can use this time frame to explore your beta desires and her with her alpha desires.
She wants two men desiring her, and wants the solid love of one man in her life. You desire the ability to serve and love her in all ways, including ensuring her sexual needs are met to the fullest in all ways. It seems you have a 30/70 relationship with alpha/beta desires at this point, and that is what may cause people to say "huh" with regards to the negative banter that may have caused you to shutdown what IMO has been fantastic sharing. The conflict you have felt is normal for those that have the ability to switch roles in a D/s type of environment, and there is absolutely nothing wrong with it.
If Spring is what you think she is targeting with her exploration, I still strongly stick by my earlier suggestions through these threads over the past year or so.
- You should really go through either honor based chastity with her telling you when and where and how you orgasm or through more traditional based chastity where it is equipment ******
- After she gets over the angst part herself, when the kids are out of the house, you should really sit down and talk to Paul about the possibility of swapping house/apartments for a few of the days. You can play the doting husband from Monday-Friday, and then share a Friday evening and go back to his apartment to stay for the weekend.
- As long as the kids aren't around, you should have them take some pictures and leave some him/her knick-nacks, so it really does personalize it that the master bedroom is "his" bedroom and "her" bedroom.
- If you and him get along fine, I would suggest you go out and have beers and become a little bit more buddy/buddy. If you feel risky, down the road your family/friends can meet him as your friend.
- Purchase a nest-cam/dropcam with her ok, so you can go full voyeur on
- While in Beta mode, you should get into a workout roll. Shave completely down like a swimmer, enforce the hairy = male view on life. If you are engaging in any chastity play, I would set goals of X pounds of lost weight, get the six pack, increase your chest size. The goal is if Paul falls to the way size, you can really work into rocking Sues life solid. Think of it as you a J.J. Watt or a Tony Romo injured and knocked out and you are getting your recovery work on to become alpha again.
- I would look into the female led relationship aspects and see if that is something she could go for. If Paul is gone or if he is around, it may provide a framework, where you can become the backup stud when she wants it and wants it now from Monday to Friday.
- Tell her you want to be her ultimate wing-(wo)man and help her get laid as much and as often as you can.
- If the conversation is solid/good, and you want the ability to flip the script, have her share what would be the most humiliating/shocking thing that you could do to her. Right now she has all the power, you need the ability to have something to push back at her. Whether it is compromising pictures, being in a situation where she has no control, bondage, sleeping with another woman (whatever) or having a lesbian take her while she plays slave to you ... come up with something that fits your two interplay.
Most of all have fun! Continue to share your feelings and angst here, as I think they will help you work out your internal "switch" conflict. There will of course be haters or folks with predefined views, and that is ok ... we are multiple shades of grey/color and all have different views.
But like I stated earlier, you should really see how deep and dark you can go, and let her push you as far as she can. Use the equivalent of a safe word, and maybe come up with a safe space act, where you leave and regain your thoughts either at a hotel or somewhere for a day or so if it becomes to intense.
I am sure there are things that sound like fantasy fodder, or things that people will disagree with. What I am trying to share with you is a viewpoint on your situation which may help you out, or at least focus on what you want and don't want.
hope that helps ... and keep on sharing we are all rooting for you ....
