tips, advice, sharing of thought processes, wisdom, personal stories all greatly welcomed. 

last year my boyfriend (23m) broke up with me(22f) and abandoned me. i have BPD so as you might know, fear of abandonment is our number one fear. 

he was the first person i ever just trusted. i thought he would always be there, because he told me so. he said we were a family. i was too mentally ill and not taking care of myself, and he left. 

i went through a traumatic time after that, and even attempted su*cide at one point. i never threatened him with it or anything, i kept my outbursts to myself. 

since then, i have gotten so much better. i am doing great these days. him and i are close again and he is being more loving than ever. again, telling me he will always want to be with me. i believe it. even while we were broken up we kept in contact as friends and how that i am doing better, our relationship is stronger than ever before. 

so, you might begin to see my fears. since that traumatic time, i would repeatedly tell myself, this is what happens when you are vulnerable and trusting. never trust anyone again so you dont ever go through this pain again. it was the worst pain of my life. 

im ready to start tackling this issue. i know it will be difficult and take time. 

what does healthy trust look like? 

how can i let go of all this fear? 

how can i believe him? 

what type of treatment could i seek for this issue?
