he forgot my birthday yay

i (20f) was talking to a guy (24) for a longer while and ofc when my birthday came up everyone around me wished my a happy birthday in the morning texts and hes ummm he was quiet- very quiet, almost like he dissapeared suddenly bruh. he knew for sure today was my birthday. i gave him a realistic drawing of his cats with hm for his birthday a few weeks ago and he loved it. we were both texting eatch other everyday, sometimes he wrote/sent me something, somewtimes i was the one texting first. it was okay, nothing crazy but seemed good for me, he seemed sweet and wanted to get to know him and his hobbies even better. and today? not even a single happy birthday gif. delicious...... seriously why do they, most of the men i talk to fail miserably so DAMN FAST like bro just try at least, at least try being a good guy at the beginning or smth, idk manipulate me lie about who you really are to me at the beggining idk try acting like a goof guy at least, but now they are too lazy for this even, this generation is cooked

im so done acting sweeter to them than they will EVER act towards anyone, they act SO LAZY or just straight up lovebomb me at the beggining. nothing in between and both are trash.

still had fun birthday and im happy that i know now that hesprobably just a lazy poop or staright up not interested in me but im seriously losing hope for a nice relationship in which i can treat someone sweet and like a princess and actually get the same treatment back, or being realistic: at least be nice to each other AND NOT FORGET SOMEONES BIRTHDAY like hello???? you asked me when i was born idk like 4 days ago? and i told you, aaaand i told you the full date 3 weeks ago as well? ik he was diagnosed with autism 2 years ago and i always kept this in mind but it doesnt change anything because he def knew what to do today. he has witndessed not 1 birthday in his 24 year old life for sure and could even copy the gifs i send him for his birthday. its not that hard to remember bro cmon. and today he also played for hoursssss with his friends on voice chat lol. i never have any problems with a guy having friends nom atter the gender as well and im happy that hes having fun but it just shows where his priorities are ig. Maybe theres a reason why he didnt text my anyything but it still made me kinda sad and dissapointed so the impact was made if i say it like this. idk if im completely giving up on him, if he comes up with an apology i will think about it and i gen want to give him a chance and be nice but i dont think hes going to do anything like this be fr, so its probably just over

thank you for listening to by ted talk with 9281 grammar mistakes, im not native and today idc about grammar mistakes because its my birthday. (btw i made a brownie and a homemade pumpkin spice latte cake and it turned out great, he didnt even have a single slice of it and he wont be getting any soon (im so evil)) we could have been doing goth makeups together, playing terraria, minecraft, talking about elden ring or other souls like while i would happily bake and cook for him inthe future or paint him or hi cats but he chose his friends so im going to keep cooking for myself and keep imagining that im a dark souls knight alone.

what do you think about all of this? what would you do?

tl;dr the guy ive been talking to for a long while forgot my birthday completely and im kinda pissed about it
