Step up or step off, Kid, you could be dead any moment, just any conversation too early with ‘ring’ in it run, run fast
One thing that I will say though, is, after you've been hurt enough and become jaded and cynical, don't also run from commitment or even letting yourself be a little vulnerable.
Like, if you've only been dating a little while and you really like her, and she tells you about a job offer she got and she asks you if she should move, don't be a dumbass playing it cool and say something like "whatever you think would be best for you." - say that you like her and that you don't want her to move, but would understand if she felt like it was too good of an opportunity. SHE WAS FUCKING TESTING YOU BRO - YOU'VE DONE FUCKED UP AND NOW SHE'S GONNA MOVE EVEN THOUGH SHE WOULD HAVE HAPPILY STAYED
and if by some MIRACLE OF MIRACLES, a year or so later after you've both moved to different cities, but she comes back into your life again through a series of very timely, happy coincidences don't double down even further on dumbass when she asks you why you would like it if she moved there because you've let yourself become so damaged, cynical, and jaded that you can't even muster up the words to say something as simple as I really like you.
IT WILL HAUNT YOU FOR THE REST OF YOUR LIFE
