so, my boyfriend recently gave me access to his instagram on my phone, and since then i’ve just been lasering in on him and his ex’s relationship. i read their old messages, go onto her profile several times a week, just generally obsess over them and what they had. i know. typical bpd thing—hyper fixate and compulsively obsessing over someone who i’ve never even interacted with! it’s a combination of jealousy and genuine curiosity. but i know it’s not healthy. i just can’t stop myself from doing it. how do i cope?
