Hey guys, this has happened to me several times.
Imagine I'm gaming a woman with bf, and when I reach C2 I have two options:
-kino escalating -> until kissing (getting buyer's remorse)
-doing nothing (getting friendzoned)

I have no morals , so making them cheat doesn't concern me at all. But even when i'm hotter and my game is tight, if I keep escalating and go too intimate (kissing) I almost always get buyer's remorse by the next day because, as it seems, most women aren't willing to cheat or to break up when they're in a serious LTR. I'm not living alone, so bouncing them to an S1 location immediately after going intimate isn't a plausible option.

Is it better to use these girls only as a DHV and bait to reel in other women or am I missing something here?

You are contradicting yourself. Stating you have no morals and then saying you get buyers remorse makes me go "this guy doesn't know what he is all about yet".

Don't worry, I get the same feeling too. Or at least I used to. Personally, I pick which ones will give me the most value as being a friend(social proof) and then I use others to be my sex buddies since I want to be a sex god. If a girl is sexually unsatisfied and she is willing to do the dirty, who am I to deny her that?

Sorry bro, I have no remorse and no morals. It's girls who get buyer's remorse.

show them affection right after. Problem solved.

Or here's a thought, game single women

I disagree. I would use to say the same thing, but if a girl is giving you heavy IOI's or is basically down, then I believe it is in the right. If the girl is happy with her man then I believe it would be wrong to mess that up. However, by default you should game single women.
