Throwaway since too many people know my reddit.

I stumbled upon TRP and it blew my mind. Seriously. I realized my entire life I have been catering to the desires and whims of women while sacrificing myself and putting myself as low on the priority meter as possible. Eventually, I learned how to be a strong man who didn't take shit from people, pushed my career forward and my life was (and is) good. The issue is, when I get into an LTR, I recently realized I flip a switch and go Beta hardcore. This has been a serial problem for me and I didn't fully understand it until I started reading a lot of information.

I am more aware of power plays and shit tests and the ridiculousness that has plagued me for many months. The issue is not new relationships or meeting new people, that has been easy enough. The differences I have seen in the way I speak to people, the way people look at me and act around me is huge. The issue is, I do want to be with my girlfriend and stay with her. I know people here are pretty fast to say drop the plate and move on, but I want to stay with her, for many reasons which aren't that necessary to post.

I made it clear to her I am making a change, I have changed within the relationship. I have noticed changes in her, but it has not been very long since I implemented the changes. A week or so. I have been less emotional, more direct, definitely avoiding the shit traps (mostly, I have messed up on 1-2), and doing a good job dictating things. I think I went a bit overboard on the dick factor and dialed it back a notch without sacrificing Alpha and without going all feminine again. I made the changes, We fucked twice the first day, took a shower together did shit in the shower, etc. We had not had sex in almost TWO MONTHS. Yeah. I always told her how much I wanted to be with her and I wouldn't break up with her over anything except cheating. I know better now, not just about telling her but about my worth. In fact, I hadn't seen her fully naked in a while (she's a bit chub

An example of the shit: Yesterday she out of the blue came home all frustrated, asking me to call someone for the ATT bill, while I Was doing something on the computer. In the past, I would have dropped my shit immediately and called. I told her I would call after I finished. She asked when, I said "When I'm done". She then gets all uppity. I've gotten pretty good at shutting down her shit, so I am feeling pretty good about that.

Sex is a problem. How can I reverse all these months of letting her just say no and taking it? Put the power back on me sexually. It seems like doing that in a non-LTR or not living together is easy, but I can't seem to find specific guidance to living together in an LTR, outside of straight up cheating on her.

How do I get her spontaneous touch desire up? I have been the initiator of non-sexual touches pretty close to 100% of the time since I was so clingy and needy, always was brainwashed to show emotion 100%, etc.

Has too much damage been done to undo? It's not about sticking to my guns because I know, at the core of me, I have changed. She will either follow suit or I'll leave.

TLDR: TRP changed my life. I can never, and will never, go back. I want to be with this same girlfriend. How do you remove the damage of many months of being Beta, and transition the relationship to you as Alpha, without giving up your power through fights, etc.

EDIT: Thanks for the replies, a lot of good info here. Much appreciated.
