i'm probably going to post this on relationship advice too but i just wanted some perspective from people who experience bpd to get some perspective on whether or not i'm being rational. 

so basically i've been with this guy for about 6 months. he has already fucked up a few times: randomly followed his ex early in us talking (he said they had a phone call and she followed him on everything. i didn't talk to him for 3 days after seeing they followed each other and then he apologized and explained. we weren't exclusively seeing each other yet at this time) , he admitted to creating a hinge early in us talking (once again apologized and explained) , &amp; he was still snapchatting his old fwb after he said he stopped (he actually has stopped now and hasn't talked to her in a long time). 

so basically he was on his phone showing me pictures from a vacation w his mom. he scrolled up too far and there was all these pictures of his ex. i couldn't say anything right then because his dad was in the room but once we got downstairs i sat there quietly for a while and was like "i think we should just be friends." 

i wanted to cry. i felt so hurt by this. his ex has been an issue in our relationship (the phone call, the first time we hooked up and talked for a bit - back in jan 2019 - her and her friends had harassed me on instagram after she saw us together at a party and sent her current bf to fight the guy, she brings me up to anyone who knows me and will ask about us and try to insult me, etc etc like basically this girl is just MEAN).

he was confused by me saying i wanted to be just friends and i said the pictures were weird and that i can't handle that. he said that he never looks at them and that he hasn't even thought about her in months. he offered to delete them and i was like "i don't want to make you do anything" and then he said okay and didn't go and delete them. i said i didn't want to MAKE him do anything but i felt like i was clear on the fact i was upset and he should've done it on his own without me needing to tell him to. 

i hung out there a bit longer. he continued cuddling up to me and saying sorry and saying all this shit about how he likes me a lot and how he hasn't thought about her at all and that the only reason he has those is bc she made him screenshot her selfies and stuff and i made him pinky promise on it but WHY wouldn't he just delete them. why?!!! 

i left after things didn't seem as weird but i was still being pretty distant. he texted me asking if we were okay after i said goodnight and i seriously don't want to reply. things are NOT okay from my end and they won't be unless he deletes those. and even then idk if things will be okay. i want to just end things i'm seriously so upset i have absolutely 0 idea how to handle this. 

TLDR; found pictures of ex gf on my mans phone. not explicit pictures but just pictures of her and it made my really upset. he offered to delete them and i said 'i don't want to make you do anything' and then he didn't delete them. he texted me asking if we were okay after i left his house but idk how to reply because things are not okay from my end. and they won't be unless he deletes them all. which i won't tell him to do. so he has to do it on his own. otherwise i am done with things i think. idk what to do or how to act in this whole situation:(
