idk I’m sad

my bf and I broke up a few months ago and it was right before summer so I didn’t have to see him for a solid two months but once school hit a lot of emotions came out. I realized that it seems like I was easy to forget. we are on good terms and talk on and off but I always see people saying how their ex misses them or something and I never got that idk it hurts sometimes like rn and idk who to turn to. I gave my all for this person and didn’t receive much back and even to do this day don’t. I don’t want them back or anything but I can’t shake the feeling of being worthless
