Well put, agree.
So apart from nexting this person, what are your five cents on how to go about rectifying this situation?
Pulling back on the sex part, dread game, keeping frame, i.e. not agreeing to make peace or silly demands and being generally attractive?
I´d stop initiating saks, this will make her wonder why. She will either initiate herself or call you out on it. If she calls you out on it, tell her your not begging or negotiating for saks. She either has desire for you and wants to make you happy or not. It is important that she has NO leverage on you whatsoever.
You are not dependend on her and she needs to know there are other women around that could replace her, which of course you never communicate directly, but she needs to know that other women find you attractive and that you have options.
You might wanna brush yourself up a bit more then usual, use the finer garments, get a new scent, hit the gym more often and become mysterious of why you do it.
I´d start to ignore her when she starts nagging for this and that, remove attention from her, she will either calm down and be more pleasant or she will call you out on it. If she calls you out on it, tell her if you are such a bad boyfriend, she needs to change circumstances. Again, dont tell her directly to piss off, but let her know you are not afraid to walk away a second time.
She needs to respect you, or she will be gone anyway sooner or later. She is not going to respect you when you try to appease her, even if she thinks she wants you to act according to her feelings. She will see you as a pushover and think she´s got you in her pocket whatever she does.
Never give a woman any leverage on you, make her think other women would want you, become mysterious/make her guess/trying to figure you out and never be afraid to walk away and make her know this.
Worked for me with my 5 last women.
