What do you guys usually talk about? Could you tell her your splitting? You dont have to tell her its her your splitting on, but it could be worth sharing with her, especially if she thinks she has BPD, maybe something worth getting off ypur chest, keeping it in is like drinking poison, those that care about you are usually willing to help, especially if theyve struggled with similar problems

Anyway, the fact that youve hung out before, shes still in vontact with you and wants to hang out are all good, positive signs of a relationship,

I sound all objective but i know how your feeling, i split all the time, its ****ing torture, like feeling your entire life falling apart, but it just means you care about this person- which is good! We're just a little more sensitive than most to these emotions so our brains go into overload, but shes still there, your still here, hold on to that.
