Did i sound selfish for saying this to him?

[Kristy]

i don't have a problem with my boyfriend not texting me back or taking forever to reply back bc i always assume hes busy with life. but what does kinda tick me is when im waiting for him to reply back i see him post stuff on instagram and liking posts and what not. i cant help but to think that hes just ignoring me on purpose. i would never do that to him. (smh hes always complaining about me taking forever to reply back. he posted a tweet saying "i hate when ppl reply slow. if yo don't reply back within 5 min, my phone is out of my hand and i will reply when im ready". so i try my best to reply back as soon as i could).

but anyway there was a day where i was waiting for him to text me back. then he stopped so i assumed that hes busy with work. hours go by and i got bored and decided to scroll through my instagram. as i was scrolling, i seen him like posts on instagram and posting pics. so i felt some type of way. then i seen him tweet stuff too. i was hurt that he was ignoring me cuz i would always reply to his messages and not ignore him.

so i called him and he didn't pick up. then i sent him this text "I am being calm but it just really hurts when you leave me hanging in the middle of convos/ignore me. If you were just simply busy, sleeping, or something like that then I completely understand. Just don't read on. But if you were ignoring me on purpose then yea it hurts. Im not saying I want your attention 24/7... I just hate being ignored that's all. & im not tryna to sound like a baby, I just want you to know what I'm feeling ...I wanted to let you know yesterday but I kinda chickened out ..but I certainly always appreciate you talking to me all together/hearing from you ..I really do."

then he called me saying that i have problems and that i was being selfish. then he went on how he was busy with school and stuff. in my text i told him that i would understand if he was busy. i don't mind him ignoring me if he was busy. i apologized and told him i wasn't tryna to be selfish. i just wanted him to hear me out. i was trying to be nice about what i texted him. if he didn't wanna talk to me i would of appreciated if just ended our convo saying he gotta go instead of leaving me hangng in the middle of convos all the time. smhh i feel like im asking for too much though. i feell like i am being selfish...i really don't ask much from him though. i always kept things to myself but what i sent him, was i really being selfish?
fyi i wasn't stalking him. i just happen to see his posts n stuff.
