What is the red pill take on the man cheating on a LTR?

Reason i ask is that i recently fucked up and accidentally my LTR found out that i was banging on the side. I was, admittedly, very stupid. Some friend of hers tipped her off that i was using Tinder and she now completely refuses to communicate with me at all. Should've seen that coming from a MILE away, but i somehow overlooked the fact that Tinder does actually display when you last used it to everyone - so i'm fresh out of excuses.

It's fine, i have enough plates on the side to not worry about the end of this LTR so much, as i was not really emotionally invested in it, like, at all. She was still the best lay i had currently, so, bummer. But life goes on.

That got me thinking, is keeping plates on the side generally a good approach when you're in a LTR, or should you try to be actually committed and faithful? Or, maybe a combination of both approaches, don't completely cut off your plates, but don't engage in actual sexual acts, just flirt, so you're technically not cheating, but still have options if things go south?

UPDATE: I held frame, and didn't use any excuses, and it paid off. After three days without contact, my girlfriend contacted me. I held frame, said i really was looking for side girls, because she wasn't cutting it (mostly true, except i was already fucking girls on the side and told her otherwise). She took the blame like a champ, said that she wasn't really seeing that and thought that i was growing distant from her. I said i wasn't, and that i said that i thought SHE was distant several times (which i did tell her), and that as long as she was committed to changing that, that i wouldn't look for any side girls anymore, but that it was up to her if we were still together or not. She said that it was OK, and that she would try harder.

The reason Red Pill helped me a LOT here, is that normally, i would've INSTANTLY admitted everything, and then tried to wiggle myself out of the horrible ditch that i would have inevitably dug for myself while trying to find excuses for what i did. Instead, i took upon the Red Pill maxim of holding frame, and it paid off big time. I went zero-contact, offered zero excuses, and when confronted, i told her in her face that her behavior is the only reason that this ever happened. Never, for one second, i admitted that i was in the wrong, no matter how much she baited me. Inadvertedly, i have played a very strong Dread Game here, even though it wasn't originally my plan, and i bet that in a few hours she is going to try and impress me with awesome fucking.

So thank you, Red Pill, for helping get out of a big hole i dug myself into. As for if i'm going to cheat again, i'm going to answer: i don't know. I'm not going to say i won't, because i found some amazing plates while fooling around, and it's hard to walk away from that. She had mentioned previous fantasies of me fucking other girls in front of her before, so, if i play my cards right, i'll end up in a very satisfying relationship.
