In my early relationships, I'd always make promises I couldn't keep simply to avoid what I thought would make her sad. I thought she'd value my consideration of her feelings, instead they we're thrown in my face, and eroded attraction. Comfort tests are more important than some retards in the comments picked up.

They're the weapons used in the battle of emotional conquest. You keep failing these, she conquers, loses attraction and moves on.

They would ask me "Will you love me forever", "Do you look at other girls" previously I'd say "Yeah, ofcourse" or "No, never" thinking I'd just made her happy and avoided confrontation. Instead she'd start coming down with princess syndrome.

Now I simply say "I don't know how I'll feel next week, keep behaving and I'll keep loving you" or "Yes, ofcourse, I do"

It, was extremely uncomfortable to be this direct at first but It gets a lot easier. You don't have to say it in a mean way, just direct. Their "I need to win over his approval" mechanisms kick into overdrive, that's how you get rewarded.

Learn how to embrace direct answers, get comfortable doing it and never avoid confrontation in favor of comfort.
