Hi Francis i took very long for me to reach out Ive had this done for a while, Kept wondering whether i should send this or not
i'm really super sorry for how I acted and the way i devalued you, your effortss, i regretted it after immediately and instantly realized i MESSEDD UPP. I hurt you when you didnt even deserve it but seriously, i did not mean all of that, even if it came off that way, I care about you, still love you more than everyone ive ever met and miss you, our friendship A LOT regardless. (jumping into a romantic relationship was a terrible idea) i was not aware i also had bpd i hate exposinf this i got overwhelmed and split due to my stupid jealousy, however i promise you i overcame this i am now a completely changed girl, very smart now and doing good, ive worked/focused on putting kindness and being honest about my feelings (telling whats wrong) first . i WILL be handling those moments better and catching it before I react instead of letting it affect how I treat you If we're ever pals again, i understand and it is reasonable if u dont want me contacting/interacting with you again as i dont expect anything from you.. but i just wanted to say i am sincerely sorry for everything not good ive done and that i hope we can at least be on neutral terms in your mind, and not think of me badly or see me as someone who hurt you on purpose anymore. 
if that’s not the case and u remain upset oof. then goodbye, thank you for the good memories we shared, thank you for the way you consistently made me feel safe, understood, and less alone, I could be fully open with you and trust without hesitation. You'll always be such an unforgettable person to me and ill keep looking back at our messages that we gladly had with a cutee smile but Whatever, Its fine ill move on If you need me to, N continue amazing! Im open to explaining further 🙇
