it's hard. i'm going thru almost the same thing. me and my ex broke up about 2 1/2 months ago. she ended it because of something i did that was pretty bad (plus we were on a break before that incident) anyway, we're still friends right now but i'm in therapy working on getting help (not diagnosed BPD, but have mostly all the traits). she said she wants to be there for me and help me, still loves me, misses me etc. It is better to get the help you need first before starting the relationship again. give some space for the both of you and work on yourself. I kno its hard and i'm trying to follow this advice as well. i feel almost empty and really abandoned/rejected, do you feel this way too? I dont believe its the end, if you can get help and if there is true love there, then it can be worked out, just have faith

and give it the time it needs to heal. Hope this helps!
