Struggling with Long Distance Relationship

hi so i’ve never posted on here but idk where else to vent so here i go. this might be long i’m sorry. i’m currently in a long distance relationship, i met my bf in college but i’m now home for the summer (across the country). i think i’m splitting on him. idek if he’s my favorite person though. recently i’ve been unhappy with the relationship. we barely text each other, i try responding to his texts as fast as i can but he leaves me on read for hours. whenever we call, it’s mostly awkward silence. i just can’t stand him rn, calling him feels like a chore to me. i struggle with bpd and ptsd and a lot of other conditions and he is very supportive so idk why i feel this way. a few days ago, it was the second anniversary of my rape, something that has been extremely difficult for me to deal with. i had nightmares and flashbacks constantly and he knew that. on the day of the anniversary, he barely texted me and left me on delivered for the entire day. i just felt very upset because he knew how shitty that day was for me and wasn’t there when i needed his support. i talked about it with him a day later but he just had a dry apology. it was my birthday a few days ago too and he barely texted me then either. he never even sent me a gift, something he promised he would give me. i feel. selfish for asking for the gift though so i just let it go. ik we’ve had many good times together but i can’t help but feel such anger and like he’s losing interest. there’s sm more but i’m just so fucking tired. he’s visiting me next month and i’m not even excited for him to come anymore. idk what to do, this is the healthiest relationship i’ve ever been in so i don’t want to lose him but i can’t help but feel so unhappy. ok rant over thanks for reading if you did lmao
