An ‘Intense Connection’ from your past, with someone who was rude, liar, and dramatic cheater, to you, who created trauma and trust issues within you with manipulation, rudeness, cheating n fickle-mindedness, coming back to you, is a NO THANKS.
Anything can change, core character can’t.
You can get the proofs of it over and over again if you have that much time and energy to go into that unhealed triggered n traumatic self that took years to heal from that shit.
Some people give such proofs even from a good distance, that’s obvio. Don’t deny that and be a fool !!
