One idea that I didn't think i'd see here, but have seen several times, is that there's a nice trick you can pull if you want to get out of a LTR or plate-relationship without drama. It goes like this: instead of just telling her that it's over, act like a complete beta and she will just drop all interest and never bother you again.

Predictions that are based on red pill-theory often come true, but too many people on here make false assumptions regarding the (lack of) inertia in the relations you try to model. To make the models seem even stronger than they are, people say that things will happen instantly. Grow balls, swallow the pill etc ---> people will look up to you like a god tomorrow. It doesn't work like that, it takes time to change people's perceptions and feelings about you.

Same thing with plates and LTRs, if you start to act beta around them, comfort them and show weakness, they will many times love it at first. They will actually often give you more sex, more affection etc, and that is why so many guys are tricked into doing it. If you commit to the 'nice break up strategy' for longer periods, you will start to despise yourself after a while. It is like a reverse fake it til you make it-effect. You lower your self worth, you internalize some of the beta mindset and soon you will have a truly dysfunctional relationship in which no one respects the partner or themselves. Since she is a woman, she will typically cling on to this relationship far too long and, yeah, to rely on her to break up is just a really bad idea. I know from experience.

There is only one good way to break up, tell her you don't want to be with her anymore.
