me and my boyfriend are nearing two years together and although we've had our ups and downs and bpd triggering events, thankfully i also learned to set boundaries. 

however, i feel extremely guilty setting said boundaries, or communicating concerns/seeking reassurance about events or people that haven't been a problem in a long time but i still haven't gotten over. 

the reason i feel so puzzled about the way i'm feeling is because he gladly, without hesitation does what i ask of him to make me feel comfortable, even with me often reminding him that my triggers are not his responsibility and if something makes him uncomfortable, he's not obligated to put himself in that position just so i can get peace of mind.

he has never reacted negatively and is nothing but respectful, provides me with reassurance for hours on end if it's needed, and is all around just the best partner anyone could ask for. it's obvious he doesn't want to hurt me and does everything in his power to keep my brain in check; that's why i am 100% sure he is not the reason for the way i'm feeling.

so why do i still feel guilty or toxic for communicating my concerns and needs?
