what is it you want people to tell you?
what you posit sounds like a glorified version of "my situation is unique / my girl is differenntttt " mentality
everything you need to know has been covered and explained thoroughly
no situation is unique or different. the variables rarely ever matter enough to get specific advice for this ONE girl youre dealing with. and honestly, you shouldnt want someone to give you the answers anyway. its yours to deal with,learn and grow from.
theres constants that will also never change and shouldnt be violated and thats where your disconnect with "universal" advice/opinions comes from.
you think its dumb to keep hearing "keep your dignity and walk away" "minimize contact" "next"?
then you go ahead and profess your undying love to that one girl you cant get out of your head
go ahead and blow up their phones and
message back n forth all day with them
tell them you like them
grovel to your ex that dumped you
try and "Talk things out" with them when theres problems
then come back and report to us.
till then, listen to the wisdom that comes from experience. you might learn something
